We have an Exchange 2003 server that is getting 8026 and 8260 errors. According to MS, you need to make sure the RUS services are pointing to a legit DC. The RUS Enterprise service is fine, points to the correct DC (named chr-dc1.imi.org). However, the RUS Domain service can't find the DC that the RUS Enterprise is using. Anyone know how I canresolve this? I'm going to run a Rebuild tonight to see if that helps. Thanks Steve Detwiler

Hi Steve, Have you checked this KB272552?

Hi Bala, Yes, i have. The problem is that when I try to select my domain controller for the RUS (Domain) service, it can't find it. It can find it for the RUS (Enterprise) service though, which is weird. Steve

can you create a new RUS and connect it to a working DC and Exchange server

Hi Lasse, I have 2 DCs in our domain. I created a new RUS and it found the one DC, but not the other DC. I checked the logs after creating the new RUS and got an Info event stating the RUS was rebuilding. Will have to wait a while see if the 8026 and 8260 errors go away. The errors ranged from every 1-4 days. I'll close this, but reopen if errors don't go away. I'm still curious as to why it only found one DC, not the other. Thanks Steve D
