A bit about current setup:
It is windows 2008 R2 AD servers (all of them are 2008R2) and couple locations which set as Sites. Each location has DFS on AD server. Roaming profiles are not used nor configured. Users have their home folder configured as mapped S: drive to DFS shared folder. For example: in profile tab user has: Home Folder -> connect -> S: to \\domain.com\dc\users\%username%
We also have redirected Desktop, Documents and Downloads folders to \\domain.com\dc\users
.
Everything was fine. Suddenly (today), users in most locations lost their local profile (both XP and W7 desktops) and got temporary profiles. Also, it looks like local profile was created today (from folder properties).
I checked events at couple machines and there is not errors related to profiles or logon process. I do not see issues in event logs at servers as well.
Basically, I run out of ideas what is wrong and why machines lost their local profiles.
PS: Laptop users do not have their folders redirected, but lost profiles as well.
