Hey everyone my first post here so be easy on me. Im having some issues configuring my server. I was working on getting the address book working on a server 2003 r2 server with lcs2007 installed. We currently have lcs2005 and it works pretty well except the address book but my real question is i configure some things in iis and got everything working for the most part. As soon as i restarted iis the front end server wouldnt start for anything i have dont tons of research on google about it and found many fixes but none of them work for me. If i try to go to services to start it from there I just get an error that says( windows could not start the office comm server front end on the local computer. for more info, review the system event log. if this is a non-microsoft service, contact the service vendor, and refer to the server-specific error code-10018124857. So i go to the system event log this is what it says there The office comm service front end service terminated with services-specific error 3286842439(0xc3e93c47). I also get an event id of 7024. So then if i go into the lcs 2007 admin console it says the front end service is stopped and the rest are running and aslo if i go to the applications it says the are enabled but all the urls are not running. please help as im going crazy with this. i cant think of anything else to check. If i forgot anything just ask thanks in advance.
