Disappearing trust relationships

[Larry Shaw]

We are managing about 850 servers using SIM 5.2. Yesterday, we had about 65 servers that did not have valid trust relationships, most with good reason.

This morning, all but three of our servers report no valid trust. When I check the servers, they have a good certificate. When I access them through SIM, they do not log on with administrator credentials.

Last week, we did remove the public community string from most of our servers, but not all. We had not added the new private read only string to the Management Server until this morning.

What task does SIM use to validate the trust relationship and update the database? Any suggestions on troubleshooting this issue would be greatly appreciated?
