Can a setup of Domain Trust bring an AD server to stop?

We just acquired a new facility where there is only one server in the network/domain. This only server is running Win2008 and is a AD domain server, a SQL ERP server and with all other services such DNS, DHCP, etc loaded.  Its AD functional level is still on Win 2000 level.
Last week, I set up the Domain Trust and this week we found this server has been brought to stop twice in the past two days. We just rebooted it and it will run like normal till next day. The problem is, do you know if the setup of Domain Trust will have a fatal impact on a AD server, especially a heavily-loaded server like this?

A Forest Trust should not have any impact on the server performace. I would start by checking the logs on the Server to see why it is failing or powering off.

The symptoms you describe sound suspiciously like those a Small Business Server (SBS) will exhibit when its EULA licensing restrictions are violated. I would recommend verifying the server is NOT running the SBS platform; if it is, creating domain/forest trusts is a violation of the SBS EULA, and you will need to delete the trust to restore normal functionality.
