We have the following Scenario
SBS Server (Main Server) to DR Server (remote Site) DFS working ok
Client moved Office with the Main server (New public IP on Virgin Broadband)
Firewall disabled on Virgin Router
Client has Cisco HW firewall in place
After the move the setup is
Virgin router Netgear 4 port Switch Cisco Firewall (Data/Mail)
We now have the issue, after the servers are rebooted DFS works fine for 25 mins, then it drops the DFS namespace from the DR Server
DFS then only works in one direction,
DR Server Main SBS server ,
Ping works in both directions ip & Name
