We finally got the new router out there and although it is slow ( 512k /sat )the tunnel is pretty stable, the issue is that I now cannot join the server back to the domain; It seems that the timeout period for DNS response is expiring before the request can be responded to; Ping Times are around 300ms from the remote site to ours it can locate the SRV correctly , however, it cant locate a DC the following domain controllers were identified by the query: DC1 DC2 DC3 DC4 DC5 DC6 However no domain controllers could be contacted. Common causes of this error include: - Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses. - Domain controllers registered in DNS are not connected to the network or are not running. NSLookup comes back in one of two ways > DC1 Server: DC1 Address: 192.168.1.8 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DNS.SERVER timed-out OR >DC1 Server: DC1 Address: 192.168.1.8 *** DNS.SERVER can't find DC1: Non-existent domain Jean-Paul Natola
