Seen this before. Use a 4.0 CMC to connect to the farm and add your first admin from there. ~DS ________________________________ From: Greg Reese <gareese@xxxxxxxxx> To: Thin <thin@xxxxxxxxxxxxx> Sent: Mon, November 16, 2009 2:37:30 PM Subject: [THIN] No Farm Administrators here's a fun one I hope someone has seen before. XA 5 Rollup 05 on Windows 2003 x64. In the AMC i have no administrators listed. When I choose Add->New Administrator, I get an error window that reads "Could not create administrator". I am running the latest AMC and tried form other servers in the farm and get the same error. I can still perform admin tasks just fine. no issues there. any thoughts greatly appreciated. Greg
