AD Site replication - RPC failed to initialise

[10forcash]

Mornin' !

I'm having problems with AD not replicating across sites, there are three sites in the domain, all running server 2003, site 1 is the central site and replicates without any problems to site 2, site 3 cannot ( or will not) replicate to sites 1 or 2. Yes, ive checked all necassary ports are open on the hardware firewalls using portqry and the RPC services are running on site 3's DC. AD sites & services appears to be set up correctly, based upon the topology of sites 1&2, all relevant subnets are listed and assigned to the correct sites.

I've tried forcing replication from all sites, still with the same error...

replmon can access all sites and confirms connections (and the errors!)

All DC's were configured and AD replicated at site 1 before being physically and logically - within AD anyway- moved to their final locations

All sites are connected by WAN links, using VSAT, all sites can see each other and logon using remote desktop and logon to http & ftp servers.

I have four other domains using the same topology all with remote sites connected via VSAT and they're quite happy....

Any ideas?

Cheers,

Are the Site Transports configured correctly for Site 3? IE: IP and SMTP

Try deleting the default or automatically configured replication methods and recreating your own.

Tguy,

Thanks -the links are ok, as verified by portqry - however...

did a bit more work with dcdiag /e & nltest, it appears that the schannel was being ignored, due to a problem with the GUID at site 3 resetting the schannel appears to have cured it. For info the command is 'nltest /server:dc1 /sc_reset:mydomain\dc2'

I ran it at both ends and forced replication, 12 hours later everything is running as it should do.....

for anyone else that has a similar problem, nltest sometimes reports 'no logon servers available' and 'no such domain' if run on the FSMO, which can induce minor heart attacks! apparently this is a 'feature' - fanx Bill!

Cheers,
