we run throught the state firewall and were running pure/IP on a 5.1 server w/groupwise 5.5. the rest of the network runs 4.1 w/NWIP IPX we have 10 servers like this in 11 offices. me have a new mis tech that work out another office and was not able to see the server so i loaded NWIP5 on it so she could do some work. that is when my GWIA stoped working. I can still get mail just can not send mail. any help would be great.
