Hello

I have a Isa Server 2006 Enterprise in appliance, the problem that
I have is the following one:

Desire to add server DC, and appears following error “RPC SERVER IS unavailable”,

Unemployment the services of the Isa and allows me to add it to the Dominion.
Resumption.

Once initiate the server is again in dominion and I can perfectly examine the Tree of the AD, but attempt to add a user of I dominate the group of the local machine, appears he himself error “RPC SERVER IS unavailable”.

The worse thing is when I have publication rules with authentication, do not allow me to validate itself.

I have monotoring and I verify that they execute protocol 389 and 88 perfectly, although fails the RPC (all interface) port 135
I have seen that continuously it fails the RPC (all interface) port 135.

In the system of the Isa server, the options of activate directory are active, I have even proven to unmark them but I continue having he himself problem.

Somebody can say that this to me happening.

To comment that sp2 is Windows 2003 and isa server 2006 Enterprise

I have proven nslookup, ping, etc and everything works

But to add a user of dominion to a local group, being the server in dominion, gives he himself error

Look at your network card Advanced settings, disable "receive side scaling" option.

Hi,

Set these keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\EnableRSS (set to 0)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\EnableTCPA (set to 0)
EnableTCPChimney and EnableSecurityFilters (both 0)
