Hey all, I have a situation with our two offices where the internet connection is unreliable. Since remote thin clients often get disconnected from the Citrix servers, the powers that be decided we should have Domain Controllers at both locations. So here's my query... What is the best practice for deploying ISA Server and Active Directory so that if the two sites are disconnected, normal network functionality will continue. To ensure access to current data, we've decided to deploy DFS Links and replicate every other night. I've never used ISA Server at multiple locations to create a WAN, only routers...
