Redhat linux: Slow start of new socket connections

  • 772

I am having problems with a Red Hat server 2.6.18.
The creation of a new TCP socket takes very long - once it is established it is fine. iptables and selinux are disabled - is there any other service which needs to be stopped?
Oddly enough I see the problem with Windows machines only.
