When you try to install Microsoft Office Live Communications Server 2003, you may receive the following error message:
Error 1920. Service RtcSrv (RtcSrv) failed to start. Verify that you have sufficient privileges to start system services.
This problem may occur if the RTCHSDomainServices group that is used to start the Live Communications Server 2003 service (RtcSvr.exe) does not belong to the Administrators group.
To resolve this problem, add the RTCHSDomainServices group to the Administrators group and then click Retry in the error message dialog box. To add the RTCHSDomainServices group to the Administrators group, follow these steps.
Note If you canceled the Setup program after you received the error message, you must run Setup again after you follow these steps.
Click Start, click Control Panel, and then double-click Administrative Tools.
In the Administrative Tools dialog box, click Active Directory Users and Computers.
In the Active Directory Users and Computers dialog box, expand YourDomainName in the left pane under Saved Queries.
Click Users, right-click RTCHSDomainServices in the right pane, and then click Properties.
In the RTCHSDomainServices Properties dialog box, click the Member Of tab, and then click Add.
In the Select Groups dialog box, type Administrators, click Check Names, and then click OK two times.
Note If you remove the RTCHSDomainServices group from the Administrators group, RtcSrv.exe will not start when the computer restarts.
