I recently created and ran a logon script for my office network, which would stealth install a couple programs and map network drives to universal letters for the entire office. I used active directory from our server running Windows Server 2003 to export the logon script to the users, running Windows XP. It went off without a hitch for most users, but in two instances the users got the error "There are no more endpoints available from the endpoint mapper" when they log on. I've found a lot of links to troubleshooting sites and posts instructing people to use DC Diag on EE, but I haven't found anything to explain what the actual problem is. If anyone can tell me what is happening here, and how to fix it, it's worth 500 points.
