Hi,

For some reason I no longer get the rpc error - strange because I haven't
even touched dns???

Anyway, now I get a different error:

The specified group type is invalid.
Facility: Win32
ID no: c0072141
Exchange System Manager

Thus I am Unable to Create RUS Instances

However, I found this possible solution in msexchange.org forums:

1. Made the server that was failing in the RUS connection into a GC.
2. Added Domain Admins group of source domain to administrators group of
target domain.
3. Forced KCC and Replication.
4. Re-ran domain prep.
5. Recreated the RUS connection and it finally worked.

My question is will this work or not? I just want an expert opinion before I
go ahead with this, just to be sure nothing breaks.

Thanks,
Taz

Taz,

This is diffficult to diagnose because you are not providing any configuration info (the ipconfig /all previously asked by Meinolf), AD infrastructure info (one domain, two domains, etc), is Exchange installed on a DC, are any of the DCs multihomed, is the domain a single label name, where are you getting this error, which domain you ran the domainprep, etc etc etc).

A good start is to let us know how many domains and DCs you have and providing an ipconfig /all of two of your DCs and of the Exchange server, and if you have more than one domain and this is occuring in another domain, supply an ipconfig /all from two DCs in the parent domain, and of two DCs in the child, and of one of the Exchange server. This will help us greatly.

As mentioned, it is believed to be a DNS issue, but probably nothing specifically with DNS server itself, rather configuration on your machines, but as I said, impossible to tell without YOUR help and info.
