We are using Unity 4.04(SR1), Win2K server, with Exchange 2000 on-box. This morning, we found that the DL that enables us to send to all subscribers on our system had been deleted from both AD and Unity (no trace in SQL either). Nothing in the event log, and no errors in DBWalker.
No one was connected to the server overnight except for a scripted insert and extract of a few fields in the UnityDB.
The only other process we have running is a nightly Message Store Manager dump, which we've set up to grab data from everyone on the "All Subscribers" DL.
Haven't called TAC yet, but thought we'd check to see if this rings any bells.
Thanks,
Steve
