We have ISA 2000 with XP clients. The system has been working well for a couple of years when this past summer ISA decided to start with a problem. No errors, just would commit. Apparently, (since I am not at this location anymore) when this happened, the school decided to reinstall ISA on top of itself. This seemed to work fine and for the most part everything seems to be responding properly except Outlook Express. The teachers cannot send or receive emails. I should say that the NEW email accounts are not working at the present nor since they are new, they have not worked. There were two old email accounts that still do work. We checked with the ISP and verified the settings. I have packet filters in place that should allow this to work. There are no apparent errors from the ISA side but I was wondering if I had missed something. Again, this has worked before the reinstallation. Other than that, could it possibly be a group policy thing and where would I find that. Thanks Bill
