Environment :
OS = Windows server 2008 R2
Lync server 2010 standard edition
We have deployed Microsoft Lync server 2010 standard edition in our environment. Everything was working fine few days before.
Recently we came across an issue that the Lync client of some users sign out automatically with the following error message:
"Cannot sign in to Lync: Please sign out at another location and try again. You have reached the maximum number of computers or devices allowed"
We have verified that they are singed in to only one device.
I tried to increase the number of endpoints using this command:
Set-CsRegistrarConfiguration –Identity global –MaxEndpointsPerUser 30
But still no luck. The error still comes randomly.
Another thing that i have noticed is that whenever this error occurs, the Time on Lync server machine changes to a random value while Date remains same.
There is nothing printed in Lync server logs of Windows event viewer.
Any guidance will be highly appreciated.
