We have a bunch of NT4 servers at work that after every daylight savings time change, the AT commands fail to initiate scheduled jobs. I'm new to my group and didn't get a chance to check out a server when it happened but have been asked to troubleshoot after the fact.The servers on on SP4 with no chance of upgrading the SP as we are eventually migrating to 2000. The fix the guys have been using is to put WINAT.exe on the server and reschedule the jobs then they run OK. Any ideas on what could be causing this and how to prevent it would be greatly appreciated.
