4.5 is not yet supported for an E2k configuration. Although the XP Windows update site supplies a link for a 4.5 Exchange version, it goes to the 3.5 version page. The 4.0 version that installs with XP will only work if you are upgrading a Win2k machine that already had the Exchange version installed.
Having it on the same server as E2k can be problematic. There is an update that can be had from PSS, no charge, that resolves some of the authentication problems with AD with a same server setup. The best solution is to run the IM from another server.

I am just starting out with the installation and am getting lost in the process. I have IM installed and active on the 2000 server. I installed the IM client (3.5) on the same W2K box and I get all sorts of authentication errors. I am trying to connect with a valid email address and password. I also would like to know how it will work with XP and Messenger 4.5.

As you can tell I am extremely new the IM world. Thanks for any help. -- Vincent Avallone iBiquity Digital (410) 872-1535 _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
