Hi,

I recently migrated my website from IIS 5 to IIS 6. However when more
than 1 user tries to access the site - I get the error HTTP/1.1 Too
many concurrent users. Please try again later. - even when only 2
users are accessing the site (I am using IE6 to access the site)

I have MaxConnections Metabase Property set to 2,000,000,000

Here's the HTTPError log:

Any guidance as to where I should look for more information will be
highly appreciated.

Thank you!
