Can't access server from desktop

Hello,

I have a strange problem. Suddenly I can't access to the server from one
desktop. I can ping server, but I cannot access with no TCP servise (HTTP,
RDP, ...). The desktop works fine, but after that I cant access any of "TCP
service" on that specific server. I can access all other server withot any
problem.

If I change the IP address on the desktop, it started work normaly. After
that I tried to use that (old) IP address on another PC and that (new) PC
stop working with this server, but I can ping it and server can also ping it
(also check arp and all MAC addresses are correct).

If I leave the desktop without any modification, the desktop start to work
after 3 or 4 days normaly.

The problem occured occasionally on different desktops with different IP
addresse and I can't find reason for that. Is there any idea?
There is no firewall nor filtering on the server.

Regards,
Lovro

Please post the output of an unedited ipconfig /all from your problem client
and from the server.
