I have a SBS 2008. When I go to the Windows SBS Console under Network --> Computers I have one computer that doesn't connect properly. It gives me the following error: Online - Do not have permission to access information for this computer.

How can I fix this issue?

This is usualy due to loss of the "security ticket" between client and server. The fix is most often to disjoin the network and rejoin. Best practice when doing so is to rename the computer in the process even if you just add a character to the end of the name. When rejoining use the http://connect wizard.

This assumes DNS is properly configured and the PC points only to the SBS for DNS.
If the firewall is enabled and ALL traffic blocked on the PC it can also cause this problem, as the necssary RPC traffic is blocked.

Should I first remove the computer name from the Active Directory, DNS and DHCP?

Commented:
I would disjoin the domain and then remove. The reason for changing the name is to be sure there are no reminants of the PC such as AD, DNS, DHCP, ARP, NetBIOS cache etc.

AD, DNS, DHCP : I know how to remove/clean a certain computer

Is there anything else I should do?

Commented:
From a command line:
Flush DNS cache:  ipconfig /flushdns
Flush NetBIOS cache:   nbtstat -R   (note capital 'R')
Flush ARP cache:  netsh interface ip delete arpcache

Correct me if I am wrong, I run these command lines from the SBS!!!

will these command lines affect any other computer on the network or not presently on the network to do people on vacation?
Top Expert 2013

Commented:
On the SBS, and there will be no negative affect on any computers. The caches are automatically updated and retained for a period of time every time a connection of any sort is made. The intent is to speed up name resolution for commonly accessed devices, but we are talking about fractions of a second.

I have just finished the steps and reconnected the client using http://connect
I will monitor the even viewer and hopefully I won't see any more DCOM
