Neil-
Can you try this:
"Value 1722 - "The RPC Server is unavailable" - Usually occurs when DNS
servers are not configured properly. There is connectivity but not at the
service level. See the Q260371 link below for troubleshooting such issues.
One note here, usually it may appear that DNS is set properly but one has to
double-check all the aspects of DNS registration/resolution as the problem
may not be that obvious. See also Q261007 - It says that this behavior can
occur if the address for the configured preferred DNS server on the client
is invalid or unreachable.
From a newsgroup post: "Do the following to ensure that the SRV records for
the AD servers are in DNS properly: (from the DOS prompt)
nslookup
set type=srv
set type=srv
_ldap._tcp.dc._msdcs.YOURDOMAIN.COM
Server: dnsserver.yourdomain.com
Address: 192.168.100.2
you should see something like this:
_ldap._tcp.dc._msdcs.YOURDOMAIN.COM SRV service location:
priority = 0
weight = 100
port = 389
svr hostname = server1.YOURDOMAIN.COM
_ldap._tcp.dc._msdcs.YOURDOMAIN.COM SRV service location:
priority = 0
weight = 100
port = 389
svr hostname = server2.YOURDOMAIN.COM
server1.YOURDOMAIN.COM internet address = 1.1.1.2
server2.YOURDOMAIN.COM nternet address = 1.1.1.1
If you don't then you definately have a DNS problem.
I would also recommend running the dcdiag and netdiag utilities on
your domain controllers. If you find that the servers aren't in DNS,
then make sure dynamic updates are enabled on your DNS server and
restart the netlogon server on each of your DCs."
