We have recently begun to experience an unusual issue with our IBM desktops. A thorough search of the usual suspects (Google, TechNet etc) has not revealed a solution and, before we draw our service revolvers and "do the decent thing", I thought I would ask the brain trust.
When a user logs-in My Computer shows two network drives as disconnected (a homedrive, L:, and a Z: drive). If the user has administrative rights the contents of the drives are those that would have been mapped during the creation of the base image for all our workstations. The connections cannot be deleted because the system reports "path not found". Since the L: drive is the drive mapped in our Users' profiles, their homedrive does not mount because the L: drive is already in use (albeit disconnected).
Rebooting the system resolves the issue and a user can login and get their drive mappings without a problem.
After the machines have sat at a login prompt for an as yet unknown period of time (at least over a weekend, possibly shorter - we are working on that) the problem resurfaces. We have only been seeing this for about two weeks and it has gradually become more prevalent. The images have been in use all year.
Current thoughts are that either a Windows or Symantec update might be the culprit. Since W2K3 closes network connections after inactivity to conserve server resources, I was wondering if there is some kind of account that is avctive on the workstation even when no one is logged in and it is that account's drives that are being disconnected?
Has anyone else seen this or something similar?
