+2 This is almost certainly backend infrastructure that is having issues. Along with what James said, check for DNS or time issues. What do your DCs look like when you run replmon or dcdiag?

I'd be looking for anything red or yellow in there that looks interesting...maybe domain authentication failures, NetLogon errors, errors from Workstation or Server services, etc. 2008/9/30 Jeff Brown <[EMAIL PROTECTED]> Anyone else have this problem? W2k3 server environment, XP Pro desktops all part of single domain AD setup. Logon script maps access to shared folders for all employees. One mapped drive for shared workspace, one for private. Frequently something happens and the mapped drives "dissapear". If you try to attach by start;run and use the unc to the folder it will typically show one or none of the 12 or so folders that are there. logging off and back on almost always fixes it back. We have about 120 desktops in 4 different offices. This problem crops up almost daily and shows up in every location. We also run Exchange, so they are maintaining a connection there as well, and we have seen outlook drop authentication too, so that they are asked for a username/password midstream, which almost always results in a support call, because it needs the domain\ info before the username when it does that. The outlook authentication happens way less frequently than the problem with mapped drives. any ideas? Been fighting this for a while. Replaced storage vault with new hardward and had hoped that this problem would go away with that, but it had no affect. Thanks for any help. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
