Microsoft OS problem

I have windows xp professional sp3 and I am not able to connect to ports 110 and 25 for email purposes. From the command prompt I tried telnet on port 110 and 25 and I cannot connect.

I uninstalled my antivirus and turned off the windows firewall and I still cannot connect.

I look on our Router/Firewall and everythings appears to be ok. The rest of the systems on the LAN can connect to ports 110 and 25.

The Router/Firewall in question is a Sonicwall.

If otherwise, the computer seems to be working, look in your HOSTS file (c:\windows\system32\drivers\etc) and see if there are any entries in it. It should all be comments.

You might also try reparing the network connection. ... Thinkpads_User

I should have noted:  to repair the network connection, log in as administrator, open a command prompt and type  netsh winsock reset.  This repairs TCP/IP. .. Thinkpads_User

Please post the output of a trace route from the affected computer to the mail server.

It should be 'tracert [mailserverIP]' from windows.

Hi Experts Exchange,

Thank you for all your comments. Appears to be the Sonicwall that is blocking outgoing ports on my system.

Take a look in the Sonicwall settings to see if your particular computer needs to be permitted. A firewall can be set up to do that, but that is normally for guest computers, not company office computers. ... Thinkpads_User

Hi Experts Exchange,

Figured out what the problem was. There was an exclusion range setup on the Firewall and my IP address was not in that range. I changed the ip address of my PC and this resolved the.
