Sharing issue with Windows 2003 Server SP2

[Rooky]

Hi everybody, I have 3 Windows 2003 Servers and it seems like the domain controller have block all user authentications because when I try to share a folder on my file server it shows the following error: The advanced page cannot be opened because of following error: the system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.

Begin with the basics.

Run ipconfig /all on all your servers and look specifically that the IP addresses, subnet masks, default gw and DNS server address is what you expect them to be.

Check that your DNS server is OK. Check that your DHCP service is OK (if used).



Cheers,
Rune

Hi Rooky,

First, you'll need to know which DC authenticated you.
This below will tell you:
Start - Run - cmd - set logonserver

Then you'll need to make sure you can establish a socket on TPC port 88 on the DC's IP address.
Try telnet DCHostName 88
Use this command to check if the conection could be established.
netstat -n | findstr 88

Use klist to purge any ticket that is no good anymore. Either that, or start over the user session.

Hope it helps.

Edgar.

If traffic is being blocked, do a tracert to determine which network devices are potentially blocking this traffic to por 88.

Hi guys and thanks for your reply,
The problem was related with a hard disk and motherboard malfunction which were about to die, now we need to buy a new server.
Thanks again!
