Fail to Remote Desktop to my T60

[wxxiong]

Not sure if anyone has experience similar problems:
My T60 works fine at begining. I can do remote desktop connect to my T60 from other machines on our LAN. However, after my T60 running for some days, suddenly I can not remote desktop connect to my T60 anymore. Every time when I tries to connect from other machine, it let me enter username and password. Then it tries to connect, but the T60 desktop screen never comes up. After about 1 minute, the connecting process bail out on the other machine without any error message.
The only solution is to reboot my T60 and everything goes back to normal again.
I usually put my T60 in standby mode when I go home and then put back in dock station every morning for work. I am not sure whether the standby/resume sequence will evetually mass up the remote desktop partion of my T60.

Thanks
