Hi Everyone, Please bear with me while I try and explain my issue with mapped drives on a Win 2008 Enterprise Terminal Server. We have an unusual setup in that the user data is stored on the Terminal Server itself on a RAID 10 Array. Most people would have the data component on a NAS or something similar but we find that the access speeds when the data is local is brilliant. The Terminal Server is a member of a Win 2003 Small Business Server Domain. Now to my issue. We originally created shares on the Terminal Server itself and mapped UNC drives via a log on script via the various Group Policies. Problem is these UNC mappings to the Terminal Server itself caused it to freeze and needed to be reset once a user tried to access a file on any of the mapped drives. Weird!!! We have done this previously on our Win 2003 server with no issues and it is working to this day. We decided to get around this issue we would use subst to map the drives instead. This works and does not freeze up the server and all works OK. We discovered and issue though when a user logs on to his profile from a second PC while still logged onto the first, the subst drives don't appear in the second session. No idea why, and there are no errors in the event log. Has anyone experienced something like this? Can anyone think of a better way of doing what we're trying to achieve? Thanks is advance... Duke
