Hi, I have a problem with have unix servers perfoming functions like telneting to an external network. Before I put the ISA server they were able to telnet out or even send email outside using mailx. Ever since the ISA server was put in place they havent been able to do some of these things and I am actually under too much pressure to have this work. This worst case scenario is I'll have to disable the proxy server. Please help out. Cheers, Mothusi
