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.
