We have MOSS 2007 site which I want users to view. But everyone who tries to open a site encounters login screen.They log in with their domain\user name and password several times and then they get access denied error. If I log in with my admin account I can see the content. I tried adding groups and users to the site permission groups such as viewers, owners etc. It didn't help. Tried to switch from Kerberos to NTLM no use. With NTLM I get server internal error screen.
Need to get this site up and running ASAP. Please advise.
