This is mostly about seeing how many others if any are being affected by this.
Servers running SBS2008 and SBS2011 have stopped recognizing destinations. I have about 11 clients running either version and each had this begin on the 16th of November, a 12th Client running Shadow Protect + Windows Backup on SBS2008 isnt affected at all.
Some are my builds, some are builds done by others. Two I inherited this week because the client changed IT providers to me and I have found this on them too.
