Recently performed a Lync Server 2013 deployment where everything was working fine until a few times a day we started receiving the below error message.
“Please sign out at another location and try again. You have reached the maximuim number of computers or devices allowed”
The error message was interesting since all the pilot users only have Lync/Skype for Business client deployed on their desktop via SCCM and we have mobility disabled so there is no way this error should be popping up.
I logged into the server and started taking a look at all the logs and found that the windows fabric service was gp faulting, with event id 1000 Faulting application name: fabric.exe
Continuing to look at the logs I found that just before the Windows Fabric Service failed there was a warning Event ID 129, LSI_SAS – Rest to device, \Device\Raidport0, was issued. Some quick searches and everything was pointing to power options not being set correctly which is interesting since this is a server and should always be running at High Performance. Primarily the PCI Express -> Link State Power Management -> Setting: is set to Moderate Power Savings
This should be set to Off as per the screen shots below.
Once we changed the settings, we no longer received the error.
