Are you sure windows firewall is turned off?
Server 2008 uses a profile based approach to the firewall settings. Again, use the netsh command but you will need to specify profile you want to configure (or disable in this case):
netsh advfirewall set <profile> state off
Values for <profile> are as follows:
allprofiles - change the settings for all the profiles.
currentprofile - change the setting for just the current profile.
domainprofile - change the settings for the domain profile.
privateprofile - change the settings for the private profile.
publicprofile - change the settings for the public profile.
If SEPM and its associated processes (Tomcat, IIS, etc..) are the only applications on this server, we recommend using the "allprofiles" profile for the command line; otherwise choose the appropriate profile.
