Hi, since yesterday I have big problems: I've got an ISA connected to the inetrnet via ADSL, I've got several servers in my LAN, including one Exchange2000-Server, the outlook clients on the workstations use several accounts: one on the local Exchange server (which still works fine), several pop3 or imap and smtp accounts which are connect ed directly to our ISP or to a web-based email service like freemail or hotmail. Yesterday I tried to publish outlook web access and the TSAC via the ISA server for our external workers. Because it didn't work I tried to change all the settings back to the orginal ones. After that the outlook clients could not connect via po3,imap and smtp to the internet. Then I tried to fallback to my backupped ISA-Configuration, which worked fine, but pop etc. is still not working. I hope somebody can show me the way back to a working configuration. Robert
