We are testing Windows 7 (32bit version) and logon to a windows 2003 domain that runs a logon script whichs maps our drive letters. We have no control over the domain. Of our 7 test users, 5 continually recieve red X's on their network drives after they logon. Double clicking on them connects the drives, however, any aplpication that requires files on the fileserver will fail since it thinks it has no connection to the drive. We have tried several reg edits (Enable Linked connections, KeepConn), we have tried to find information in the event viewer to no avail. We have also looked at any differences in NIC driver versions (none). The other 2 computers that can connect without problem are local admins, but, if we logon to the 5 that have the problem with the local admin credentials we get the red x's as well??? This one is a real head scratcher......
