Hi, Question: OldDomain = FLastNameNewdomain = FirstName.LastName Here is a little context information. I have this site collection that was created when we have 2 domains. The server is on the OLDDOMAIN and the user accounts, security groups, DLs are on the NEWDOMAIN. This works fine.When I created the site collection and the site admins started added users, they made the mistake and added the old domain accounts. When i found out about this, I removed them from the peoples/groups and ensured that only NEWDOMAIN account groups were authenticated. As well, I I placed a site collection filter on the site collection for the people picker to only find accounts in the NEWDOMAIN. This worked too.The issue is that the few users that had there OLDDOMAIN account added accidentally appear in the dropdown list when saving files to a document library.I cannot find were this is cached. I have recycled the appPool, rebooted the server and checked the site collection DB.Content DatabaseSELECT *FROM UserInfoWhere tp_login = 'OldDomain\FirstInitialLastname-> No record foundSELECT *FROM WebMembersWhere userid = 56-> No record found. 56 was the user ID before the user was removed. I have browsed to the site collection "/_catalogs/users/simple.aspx" and they are not listed. I also tried to remove the filter on the site collection to see if they were listed.stsadm -o setsiteuseraccountdirectorypath -url http://www.domain.com/dev -path "" Still no go, Any other ideas?Hades666

Have you tried to use Migrateuser: Stsadm operation (Office SharePoint Server) (http://technet.microsoft.com/en-us/library/cc262141.aspx) command? It should be helpful for your issue.Sincerely, Lambert Qin Posting is provided "AS IS" with no warranties, and confers no rights.

Not quite the answer I was looking for, but thanks for replying. C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN>stsadm -o migrateuser stsadm.exe -o migrateuser -oldlogin <DOMAIN\name> -newlogin <DOMAIN\name> [-ignoresidhistory] C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN>stsadm -o migrateuser -oldlogin OldDomain\FirstInitialLastname -newlogin NEWDOMAIN\FirstName.LastName The specified old login name could not be found. No records had been updated. C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN> As I mentioned earlier, the user is not listed in the Websusers table and the site collection is filtered. Thanks, Hades666
