Thank you for all your suggestions,
Unfortunately I still need help as our site remain on IIS till I can fix our isssue.
We are using SME 5.6U4 on Dell Poweredge Blade
what I do not understand actually is why cant I acces our web site even by the IP address, it ping it but the requested url could not be retreived. Internally by using the address IP, i can see the site OK, but externally, I cant get the site at all, before it was slow, now it's worse
I test the cable and the ip with a second blade on red hat and it work fine, no ip conflict and no firewall issue ahead. I thought the dual ethenet pci-x card was faulting but even with Intel Pro100+ I get the same result. It's strange. I updated to 6.0 beta 3 and no difference I can get from internal IP addres but not from external IP address, I use some contribs like service, monitor, freetds(connect to mssql DB), dev-tools from contribs, that's about it.
Also, after I try the internal ip for the site, and got there succesfully, I went to see what's in the httpd/error.log
I can see these following message:
[notice] Accept mutex: sysvsem (Default: sysvsem)
[notice] Cought SIGTERM, shutting down
[notice] Apache configured -- resiming normal operation
[notice] suEXEC mechanism enable (wrapper:/usr/sbin/suexec)
Help would be very appreciate.
Thanx a lot for your precious time
