network printer installation problem

Hi everybody
I am trying to install a network printer with ip address 192.168.40.11 but STANDARD TCP/IP PORT is not available in the windows xp to add.But when I try to install any local printer also I am getting the error posted
Kindly anybody please help in this regard
Operating system windows xp sp3
The error report Iam getting is as in :

User has admin privileges
Iam facing this problem in only one pc in my domain .I tried to install in other pc's;found there is no problem in printer as well my domain's active directory also
Please kindly help to get the printer installed in that pc since it will be a great pain for me to backup ,format and reload the pc
N.B: Past two days I googled and applied the registry tweaks but there is no effect
Thanks in advance

I might have rebooted the pc around 50 times
Any solution you can suggest?
Thanks in advance

I solved the problem by dowloading cleanspl utility from microsoft and deleting all the printers and uninstallling all the printer drivers and rebooting the pc and installing the printer again solved my problem
