I have a 4 PC home network that runs a w2k workstation, 1 XP with SP3 and 2 PC's with Vista Home Premium. One of the Vista PC's runs as a small network sharing server (ie shared folder for all home data) Everything has been fine with the w2k and xp PC's connecting to the Vista PC Data share. Today both Vista PC's had SP2 installed and then rebooted. Now the w2k and XP PC's can no longer connect to the Vista Data Share. They are either coming up with "Access Is Denied" or a credential box asking for username/password. No matter what you put in for username/password ir just keeps bringing up the credential box again. Searched Bing but could only find this page with this statement " Bugs and issued fixed on a Windows PC after installing Vista SP2 . On a Windows XP-based computer, you cannot access subfolders and files in a share folder in Windows Explorer if Access-based Enumeration is enabled for the share folder" Now this is what is happening to me but I can not find any info about Access-based Enumerationfor Vista SP2 Can someone help me here? PS, I have recheck Network and Sharing and all settings are correct like No password sharing of files and yes to share my files and folders. To recap All was fine untill Vista SP2 was installed, then the w2k and XP PC's can no longer connect to Vista shares. I have even tried creating new vista shares and still the w2k and XP PC's can not connect. The Vista PC's can seek and access each other just fine. I should also say that the w2k and XP PC's can not connect to the other Vista PC not even the public folders, whereas yesterday they could. Re-edited: 4 hours later... I have just uninstalled SP2 of the Vista PC with the data shares on and the w2k and XP PC's can now see the shares correctly and access the data just as they could of done before. So what is in SP2 that stops the shares being accessible to NON Vista PC's?

Blank password on the Vista side causes logins to reject due to "user restriction," or words to that effect. Password is not required on the non-Vista machine. If the Vista machine doesn't show the non-Vista, type on the URL line \\(machine)\(valid directory). When I do it, the non-Vista machine magically appears on the left side of Explorer and I'm in the directory.
