the semaphore timeout period has expired securecrt 8.5

The Timeout could be related to several parts on the hardware and/or probably to some software as well. Recentley we where supported by a microsoft engineer for a project and aksed him if he was familiar with this problem but he also was scratching his head again and again.Īs mentioned in the opening text this is still a random issue which occurs every now and then. I Entered this on the Microsoft Helpdesk (we've got platinum support) but they cannot solve this either. This problem still excists and no cause can be found.

Who delt with this issue before and /or can help me out on this?
