I have Crystal Reports Server XI newly installed on a machine in the UK. I have the client software (i.e. infoview) installed locally here in the US. When trying to log into the CRS I receive the following error: Transport error: Communication failure. If I use the http address to the info view on that machine, I do not have a problem logging in. I'm sure this is a firewall issue of some sort. I have added the usual ports into the firewall (6400, 6401, etc) but I am still receiving an error. Could anyone advise what else I should check? I am able to connect to an other CRS in the UK so it's not a communication issue with the network. I can ping the new machine that the CRS XI is on without a problem.
