Hi, Looking for help in cross forest setup with single sccm server. My scenario: Primary forest A: SCCM installed and configured, working well. Schema is not extended, published MP in DNS and using SLP. We have another forest (Forest B) in same building in another VLAN, and we have one way trust to that (from A to B) I configured SCCM Site server computer account to have read access in ADUC on Forest B DC. In active dierectry system recovery, LDAP:// is added with correct DN. forest B's VLAN is configured as a boundary (Not sure this is required if AD discovery can discover computer from Forest B). SCCM discovered all client computers in Forest B in "all systems" collection but when i push client to computers it doesn't work. I do configure client push installation with Forest B's domain admin group member account. I created a custom collection to list all computers in Forest B with AD system name, but nothing is listed there. But if I check in all system collection I can view all Forest B Domain computers. Am not sure this is the correct setup I should do in this scenario. General DNS setup: We have only one DHCP server and it is in Domain A (Forest A) and this is used in both Domains (Forest A and B). All clients using (Forest A and B) one dns server which is in Domain A- Except Servers in Domain B (Forest B). Conditional forwarding is configured to Domain B. I am new to sccm and searched a lot on this but couldn't find anything helpful. Your assistance is highly appreciated MCSE

Which error are you getting when trying to push the client? See ccm.log on the siteserver. You can try to push one client within the All Systems collection. How does your WQL query for that custom collection look like?

Hi, You need to find out you should start the troubleshooting. Verify that you can push the clients by looking at the ccm.log file If the push is succesful then check the ccmsetup.log file on the client. It could a permission related problem from the client side when connecting and trying to download the needed client files.

Thanks for your replay, I tried to push some of the clients in Forest B from All Systems now, I succeeded in two of them, but some of them gave me error which is bellow. ============= CWmi::Connect(): ConnectServer(Namespace) failed. - 0x8004100e SMS_CLIENT_CONFIG_MANAGER 11/26/2010 8:22:23 PM 29524 (0x7354) ---> Unable to connect to WMI (r) on remote machine "COMPUTER NAME", error = 0x8004100e. SMS_CLIENT_CONFIG_MANAGER 11/26/2010 8:22:23 PM 29524 (0x7354) ========= I think this is a WMI error, which i can fix some how later, am i right? Changes i have made since last attempt are: I reset the Domain admin password which i used in "client install account" for Forest B. And typed it again there. May be i had mistyped the password. But some more questions remaining. 1)ccm.log says installation was successfull in two computers, but i can only see one in "All systems" as client installed. 2)The one i can see in "All systems" was not automatically approved. And I have a custom collection called "All client installed computers", in which this new Forest B machine is not listing. Custom collection for Forest B, query is bellow: select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ADDomainName = "ABCD.COM" Now I badly need to have a custom collection for Forest B to push client to all.

Thanks for your replay, I have pushed clients to couple of computers (forest B) from All System and two of them completed successfully and two of them failed. Error as bellow from ccm.log ============ CWmi::Connect(): ConnectServer(Namespace) failed. - 0x8004100e SMS_CLIENT_CONFIG_MANAGER 11/26/2010 8:22:23 PM 29524 (0x7354) ---> Unable to connect to WMI (r) on remote machine "COMPUTER NAME", error = 0x8004100e. SMS_CLIENT_CONFIG_MANAGER 11/26/2010 8:22:23 PM 29524 (0x7354) =============== I doubt this is WMI issue and hope I can resolve later, am I right? Changes I made since last time are: Reset Domain Admin account (Which configure as Client Push install account for Forest B) and entered again. I may misstyped password before. I also removed "Install client for computers on this site boundary..." check box on Client Installation wizard. Still some issues remaining: Out of two clinet installed computers, only one is listing in All Systems Collection. Clients are not autocratically getting approved. These two computers are not in my custom collection "All client installed computers" Now I need a custom collection for Forest B computers to push client for all (Normally I push client first and setup start up script for failed computers). The query for my collection is bellow, which list nothing in it. select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUn iqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ADDomainName = "ABCD.COM" MCSE

Hi, For a custom collection for all computers is in a domain, my query was wrong, right one is bellow :) select * from SMS_R_System where SMS_R_System.ResourceDomainORWorkgroup = "DomainName" MCSE

Hi, For a custom collection for all computers is in a domain, my query was wrong, right one is bellow :) select * from SMS_R_System where SMS_R_System.ResourceDomainORWorkgroup = "transguard0" MCSE

I assume this one is solved now. Marking your post as the answer.Follow me through my blog and Twitter!
