When doing some exchange powershell you would probably get this error or somthing like it sooner or later:
Connecting to remote server failed with the following error message : The WS-Management service cannot process the request. This user is allowed a max imum number of 18 concurrent shells, which has been exceeded. Close existing shells or raise the quota for this user. For more information, see the about_Remote_Trouble shooting Help topic. + CategoryInfo : OpenError: (System.Manageme….RemoteRunspace:RemoteRunspace) , PSRemotingTransportException + FullyQualifiedErrorId : PSSessionOpenFailed
Workaround for this is to recycle the MSExchangePowerShellAppPool Application Pool
When calling some foreign numers Lync server CANCEL the call when it is in progress. Network sniff shows that the call is terminates after 10 sec.
This is a default value of the Lync Routing engine. The value is located in “c:\program files\Microsoft Lync Server 2010\Server\Core\OutboundRouting.exe.config”
SOLUTION:Replace value “FailOverTimeout” value 10000 with a value of 20000. Reboot server. Remember to do this on every frontend server that is involved. You will have to reboot involved servers for this to be activated
<configuration> <appSettings> <add key=”FailOverTimeout” value=”20000″/> <add key=”MinGwWaitingTime” value=”1″/> <add key=”MaxGwWaitingTime” value=”20″/> <add key=”FailuresForGatewayDown” value=”10″/> <add key=”FailuresForGatewayLessPreferred” value=”25″/> <!– Valid values are between 5 and 600 –> <add key=”HealthMonitoringInterval” value=”300″/> <!– Valid values are between 60 and 3600 –> <add key=”GatewayStateReportingInterval” value=”1800″ /> </appSettings> </configuration>

This error is because you have several OU’s named “Users”. Edit the scrip to use a spesific OU, i.e “CN=Users,DC=test,DC=local”
Got this error on “Computer\System Protection\Bare Metal Recovery” and “Computer\System Protection\System State” , turned out I had forgotten to install windows feature “Windows Server Backup Features” on the client.
After updating my HTC Mozart to update 7740.16 I got internet connection sharing, but one problem arised. The WLAN mac address changes every time I restart by phone. This is pretty annoying since my WLAN uses MAC validation. 🙁
I made a simple powershell to list server accounts in AD, list versions and service pack level. It will also do a simple test-connection to see if it is alive (remember 2008 firewall will block icmp by default.
