I'm having some problems with accessing one network (protected by ISA Server) from another network (protected by ISA Server) utilizing PC Anywhere, and "other" remote tools.. I can access these remote tools just fine from any other exterior network not utilizing ISA Server. ISA on these networks is working just fine (web servers, FTP servers, etc...).. What type of port access or permission access do I need to establish for the two to talk to each other via PCA and/or Terminal Services...Do I have to establish a specific permission set for each network to access the other....? Any thoughts.??? Glen Howard II, MCP Systems Administrator ghoward@xxxxxxxx <mailto:ghoward@xxxxxxxx> "Let's talk about it later, Let's WORK on it Now!!"
