Y: Drive Not Mapping on Reboot

System

We are on TS 5.5.2 SP3 on Windows 2000. We have made no upgrades to our production server for months. We reboot our server nightly. However, this morning, when the server rebooted, the Y drive didn't automatically map. All services are started, but when I try to map the y drive manually (using \\iwserver\iw-mount), it says that \\iwserver\iw-mount is not found. Users can see the login screen but get 'invalid username' whenever they try to log in. We have rebooted numerous times (we had this issue about a month ago and a random reboot seemed to fix the problem).

When we do an iwstat or iwreset -a, we get that there is no server found. There is no helpful information in any system or Interwoven log.

We are currently working with Interwoven support because all of production is down, but after 5.5 hours, they haven't really made any suggestions yet. Does anyone out there have any ideas?

Thanks-
