Hi all. I got this problem with setting up a homegroup with my 2 computers. My laptop manages to create a homegroup, and I get the password for it. But when I try to Join homegroup on my other computer, i get the "Windows cannot set up homegroup on this computer" (Error code0x80630801). I've also tried creating the homegroup from comp2, but same error pops up as soon as i hit the Create button. I've tried looking up the error message, but with no real results. Any ideas..?

Both machines need to be running W7. Home group will not work with any other OS and W7

Dave____J said: Both machines need to be running W7. Home group will not work with any other OS and W7I doubt he would be able to join a homegroup if he isn't running W7 on both systems.

I can't reproduce this particular error, but I've also had my fair share of problems trying to set up a homegroup. Creating and joining one went without a hitch, but actually getting to share files and resources was apparently too much to ask. :-pI've reverted to bypassing homegroups and using the old fashioned manually shared folders - it works just fine.

Yeah I am using W7 on both computers :) And I am able to share stuff the old-fashioned way with shared folders, i'm just curious about this W7 Homegroup thing :) If you google the error code you get this description: "The Identity Store has been corrupted. Delete idstore.sst from the %appdata%\peernetworking folder. Value: 0x80630801" I can't find the idstore.sst file it mentions. The closest one is the idstore.dll in the system32 folder, and windows won't really let memess with that file...

It seems there are still a few bugs left iron out. Homegroups are an important new feature of the Windows 7 experience though, so Microsoft will have to fix it anyway before they can throw the final release out there.

This is an old post but found file under ...windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworkingHope that helps

This is an old post but found file under ...windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworkingHope that helps Hey again. Haven't checked up on this thread before now. Thanks Alot! I deleted the file, and the error was gone! Don't know why I couldn't find it myself, think it was because I needed some administrator rights somewhere...

You rock.I've been trying to fix this issue on Windows 7 RTM for hours now (including the proverbial "I give up let's reinstall" - LOL)Deleting the file idstore.sstunder windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking fixed it.I didn't even need to start the services.. shazaam they started themselves!

I'm having the exact same problem, only I don't have a folder named "AppData" under windows\serviceprofiles\localservice. Any other ideas?

It's hidden. Try changing your settings so you can see hidden files then you should see it.Deleting the file didn't work for me. I still cannot conect my computers using the Homegroup feature. I've given up and just use regular network sharing. Gregory I. Hayes

I changed the settings to show hidden files, but I only have "idstore" and "idstore.sst.new" in my PeerNetworking folder. I tried deleting both of them but they come back each time I try to join the network. I still cannot use Homegroups.

I gotta stop playing with this (not). I have more trouble with my own pc than I have with any at work or even the wife's. Deleting the file idstore.sst under windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworkingworked just great for me. I had to manually start the services but they started right up and didn't geive me either of the errors. (0X80630801 and the 1038) Finally a forum that actually has some answers.

I am having the same problem. I set up a homegroup on my laptop and my net book and they work just fine but when I try to add my new desktop I get that same error. Im new to all this networking stuff but was wondering if it has something to do with my laptop and netbook having 32 bit operating systems and the desktop having 64 bit.

It's not a 32-bit / 64-bit issue. I've got 3 computers running 64-bit Home Premium and none can connect using Homegroups.Gregory I. Hayes

Hey i have a problem with it, here is my sitch, laptop - win7 ultimate pc - win7 ultimate i create a homegroup (doesn't matter which one) and it sets up fine, password and everything, on the other machine i hit join, it searches for ages (it says it can join and reconizes it) but after a while it doesn't join or just says 'windows cannot set a homegroup on this compute' this is on both of them, running win7 i've tried everything, firewall off, the homegroup password thing off, searching through loads of files and changing varibles, then back to normal after the didn't work. What am i doing wrong? can someone please solve my annoying family home pc problem, cuz i can reli use this for college work (printing, files etc) thanks, Rowan

i coundnt find the foleder PeerNetworking....what to do now...my hidden files setting are set to VIEW HIDDEN OR SYSTEM FILES...

Had similar problem,2 computers running win 7,could see files but could access only one way.Im running eset 4 and zonealarm.Eset has file protection,I excluted the drive Im shareing and now transfers work both ways. I spent two days trying to configure router ,firewall ,folder permissions,ect,ect.HOPE THIS HELPS SOMEONE

So do yuo have Homegroup working, or just regular network sharing?Gregory I. Hayes

Dan Wireman IT Support Specialist I am having the same problem. First o f all I would like to thank IT Support Specialist, Dan Wireman for giving the exact location of the idstore.sst file. I also had tried to find it by “showing all hidden files” but, couldn’t find it. I couldn’t have found it without your help Dan, thanks again. I had to confirm Administrative Permission before I obtained access to the file. However, I am still not able to set up a homegroup on this computer. I have tried to set up a homegroup immediately and after a reboot. After I immediately try it when I just deleted the file I get the error, "Windows cannot set up homegroup on this computer." I checked the “PeerNetworking” folder again and the idstore.sst file is still not there. I rebooted the PC and looked in the “PeerNetworking” folder again and the idstore.sst file appeared in the same spot only bigger than the one in the recycle bin that I just deleted. I am still not able to set up a homegroup without success. I also tried the Homegroup troubleshooter with no success.

I got it and it was simple!!!!All I had to do is "leave the homegroup" then set up each of the computers up individually with the same password of course (just as I was trying to do before). For some reason it wouldn't let me use the same password or any other password for that matter. Any how, I got the all the computers working together as a whole now. I can even print using one printer now. Now, if I could just figure out what I need to hook up my big screen TV wirelessly like the guy on the Windows 7 comercial did I'll be set. I think I got to get some kind of router like a Slingbox, wireless router (w/HDMI plug) or a Roku player. Why do the best things Windows 7 has to offer have to be so difficult? I had this question on Ask Yahoo for a montha and no response. I hope I have helped someone out there and Bill Gates, If you read this, just because you have cornered the market doesn't mean it's okay to forget about your customers after you take our money. I wish I could give this head acke to you and you will start to understand what I mean LOL. Just kidding, I wouldn't want to wish any harm on you. I think you have done great with Windows 7, now you can work on CUSTOMER SERVICE and a warantee. Thank You Everyone!!!!

I managed to sort this, I deleted everything in the folder C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking\, removed my main PC from the homegroup and the started again settting the homegroup up. Sorted Hope this helps someone out there!

OK, followed LL Cool Duck's approach and it worked! Thanks!

THANX! this solved my problem too. if you are still struggling to find the "AppData" folder, try typing :"C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking" into the search on your startup menu. Then you will find it, you most probably have admin rights blocking you from seeing the file, but it is there.

Turns out Symatec Endpoint was blocking the IPV6 traffic for me. I had to disable Network Threat Protection and enable Windows Firewall.

I still cant find the AppData even by typing C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking into the search menu.

I did everything that was said on this page...the peer services are running on both my pc and laptop...and still i cant connect to the home group ived created...

I had the same problems and spent several days reading and trying everything I could think of and all the suggestions here. Figured out I needed to remove my drive protections in my system restore. No problems after that. Hope it helps Don't like not having the system restore feature but it was the only way I could get it to work.

This is what fixed mine. I pluged the wireless laptop directly into the router and join, after that unplug and reenable wireless. Another fix was to reshare the homegroup folders even though they were already shared. Soon as I shared again, was able to join and see the folders.

I have just been through volumes of forums discussing the problem of computers not seeing one another on the network. I have a decent computer background and work at a college that does computer training. My two computers ... a desktop (using Windows 7 Pro) and my laptop (using Windows 7 Home Premium) initially setup Network Sharing using homegroup initially very easily and worked flawlessly. Suddenly without cause or explanation, one could not see the other. I have never been more frustrated than trying to get both of them to see one another again. I have gone through every F&Q, forum, and everything else one could imagine and shared the frustrations many other had found also ... nothing seemed to work. All settings were as recommended, all clocks were in sync, the router was reset, I left homegroup on both computers and set back up a homegroup and got a new password on the Windows 7 Pro, and I then tried to join on the laptop (which initially would not let me join), all planets the solar system were were aligned, the proper chants and sacrifices were made and nothing seemed to work. Argg! This is what I did discover and there is one item in this very forum string that did work: After I created the new homegroup on my desktop, got the new password and checked everything I wanted to share, I found the laptop still could not see the homegroup to join. I did discover, however, that if I went back to the desktop, went to my libraries, right clicked one of my libraries, in the menu selected "Share With" and selected "share with Homegroup" suddenly the laptop could find a homegroup to join. I followed the "join homegroup" process (on the laptop)and put in the newly created password I created from the desktop. The laptop now saw my desktop. It was a sort of "Eureka!" moment. I then found the desktop still could not see the laptop even if went to the laptop libraries to do the same right click sharing and selected a "share with homegroup" option . I thought then that perhaps a reboot of both computers might resolve the problem. I did that very thing and upon reboot, I was back to square one. Neither computer could see the other. Now, the moral of this story ... I tried one thing mentioned above that instantly allowed both computers to see each other. My desktop is directly connected to my router. The laptop feeds to it wirelessly. I connected my laptop directly (hardwired) to my router and poof, both could see each other and the "homegroup" was a happy family again. I am wondering how many people that have the problem of their computers not seeing one another have a desktop directly connected to their router and a laptop that connects wirelessly. It could well be that there is a bug in the wireless connection process or a setting that has changed not covered in all of these forums that is causing the problem. Connecting both computers directly to the router seems to work, however. Any thoughts?

Google's Gbridge certainly seems to cause problems with this. I turned it off on both the desktop and laptop, "left" the Homegroup on each, rejoined, and it finally worked. Now I see that GTalk server is attempting to connect upon reboot but is unable. I suspect you can't have both running and so much choose.

Wheh I connect the laptop to a hardwire homegroup seems to work etc. but fails on wireless. Anyone else have any ideas?

Yes, deleting the idstore.sst file from windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking solved the problem. I was able to finally start the "Peer Name Resolution Protocol" after removing this file and i can now join the homegroup. Thanks for the post.

I think that some of the earlier posts involving wireless might be the key to my problem at least. When setting up my homegroup I had IPv6 disabled and it would not create the home group until I enabled it. I have my other windows 7 box connected via wireless and am pretty sure my wireless does not support ipv6. I am thinking that this is the problem. Any thoughts or ideas?pcgalen

Helped me. I uninstalled ESET and everything including Window Remote Assistance Easy Connect, Ad hoc connection, and joining homegroup worked. Apparently, there are features in firewall like ESET that blocks all incoming computer from connecting. Thanks!

I have no idea what single step fixed if for me, but it is fixed now. Here is what I did: Had all the other machines, including the one I am on, leave the homegroup. No machine is on the homegroup. Deleted the file idstore files from here: \Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking (For those having trouble with this step, note that Windows is not always installed on Drive C. Type in what I show, and you won't have to worry about the drive.) Went to Services (Start menu, then type Services.msc), and restarted/Started the Peer Name Resolution Protocol Set up a new home group Joined the homegroup again from my other computers It worked for me. - Charlie
