We setup mirroring and everything worked fine. The server with the backup database was relocated to a remote site on our WAN. It was offline a couple of days. I believe the server was just shutdown without pausing the mirror. Now, both ends say disconnected and I cannot get them to sync up. Both servers can talk to each other, the SQL management studio is able to open both SQL servers from either end.
I have tried alter database <db> set partner resume from both ends which had no affect.
