I have an AD DS server running Win 2k8 R2. I have a GPO for Drive Mapping through Windows Preferences, linked/enforced at the domain level, and security filtering is performed by group. I have a user who is a member of said group. I have no problem using GPO Preferences to map drives which exist on a Windows Server. However, I have several network shares which reside on an IBM i Series server and one Linux server. When I try to deploy these drives through GPO Preferences, the drive icons do show up on the client computers. When I log in as said user, the drives always show as disconnected. The drives which point to shares on Windows servers are fine. When I double-click the icons, I receive an error message that the username is not found with error code "The user could not be found 2221". It seems like it's trying to authenticate to the foreign servers with a domain account. I can manually map these drives, but they show disconneted at next logon. If I specify a username/password in the "Connect as" fields in the Drive Map Preferences GPO, it seems to have no effect. It doesn't matter if I use replace, create, or update in the GPO, the result is the same. All client systems are Win XP SP3 w/ XMLLite and GPO client side preferences update installed.
GPResult on the client systems shows that the GPO is applied with no problems. I'd really like to avoid using Logon scripts to achieve drive mapping for these shares, but increasingly it appears this is my only option. Can anyone shed some light on this??
