This solved a couple of issues for a client of mine http://support.microsoft.com/kb/930045 From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Toby Sent: 25 September 2008 09:03 To: thin@xxxxxxxxxxxxx Subject: [THIN] Tsreboot on Citrix Presentation Server 4.5 Advanced Hi List, I use the tsreboot utility to restart my servers on a weekly basis. The utility is great, however, for some reason two of the 30 Citrix servers we have fail to reboot. There is nothing in the event logs to show that his has started/failed or anything remotely involving a request to restart. Is anyone else using tsreboot and having a similar issue? Many thanks Toby
