Here's a unique issue I came across the other day that I thought you might like hearing about. In this case, we were unable to connect to a ConfigMgr 2007 Secondary Site server from Tools => Service Manager unless we were using a domain admin account.
When attempting to connect to the Secondary Site server in Service Manager we received the following error message:
ConfigMgr Service Manager
Error communicating with the specified ConfigMgr Site Server
This error can occur if the SMS Groups do not contain the proper Site Server computer accounts.
You may also receive the following error when attempting to connect to the Secondary Site server in Service Manager if the logged on account is not a member of the Secondary Site Server's Local Administrators group:
Access to the specified server has been denied. You might not have enough security rights to complete this operation
SMS Group membership and/or Local Administrator group membership configuration is not configured correctly.
We found that the ConfigMgr Site Server Computer accounts were not added to the SMS_ groups correctly on the primary site server local groups. To resolve this we did the following:
Once we completed these three things the connection from the ConfigMgr Service Manager tool was successful.
In some cases you may want to see if it is possible to get this to work without the account being a local admin on the Secondary Site server, however, this does not work in all cases and the TechNet article below outlines this:
Service Manager In Configuration Manager 2007 Service Manager, you must have the Administer right on the primary site object to perform the following tasks:
On a secondary site, you must be a member of the local Administrators group to perform these tasks.
