I am an administrator for a small network, and we're running Windows 2000 Adv Server and Exchange 2000. I've used the default settings for OWA, and people have been using it fine. However, in the past week, no one can login to OWA anymore exept for those in the 'administrators' group. I can add and remove people from that group, and they have/don't have access respectively. I don't think I've changed anything, but I can't find any access/rights area in the IIS/OWA settings. Does anyone know why this would be happening, and how to grant access for everyone to login again? FYI, when someone tries to login who isn't an admin, it just goes to a blank white page with 'access denied' at the top. Thanks! Mikel

It could be a permissions issue in the \Exchsrvr\bin directory! That subdirectory has to have read privileges assigned to "Everyone" and "Authenticated users" need to have execute permissions! Also make sure that the Users (or group) you want to give access to the OWA have the right to "logon Locally" on the IIS Server that hosts the OWA. If you run Windows 2003 Server: check your GPO group policy objects. On the 2 hosted directories on IIS (/exchange /public ) use only Basic Authentication.... Anon. Access on /Exchweb Good luck!
