I'm running Listserv 1.8c on NT4.0 server. I was running IIS3 and everything was running fine. I just installed the IIS4 upgrade, made no changes to Listserv and a curious thing has happened. The web archive works when selecting a particular archive but not when you do a search. A search request returns the below error message in the browser: Unable to initiate communication with LISTSERV. Error code was 5 ("Access is denied.") The server is probably not started. What could be wrong? Remember.. selecting a particular archive works. So WA.EXE can see the archive files. In other words: http://mysite.com/WA.EXE?A1=ind9712&L=mylist" works ok http://mysite.com/WA.EXE?S2=mylist&q=test" does NOT work ok http://mysite.com/WA.EXE?S1=mylist" to even bring the search page up even works Thanks for any help! I need it! -Dan
