Endpoint Protection

I recently install SEP on Windows Server 2003 + ISA 2004+RRAS and after reboot I found than all my network interfaces have lost at Network Connetions and server become unavailable from network. Network connections was empty.

I try to start and stop service "network connection" but no luck. Then I try to uninstall and install network interfaces through device manager. After this Network interfaces are show up at Network connections and i can start the network at this server.

Now Internet Access at this server is working, but RRAS server could not start. When i try to start the RRAS the next error is logging at the event log:

Event ID: 20103
Source: RemoteAccess
Description: Unable to load C:\Winnt\System32\Iprtrmgr.dll

I start tracing for RRAS. Here is:

I think that problem is with Virtual Interface for VPN connection: when I manualy configure server for NAT only it starts with no errors, but when i enable remote access, RRAS server could not start. Uninstallation of SEP does not solve this issue.I 

I try search google to fould the solutions, but all those solutions not working for me.

I need help! :)

Although I am sure this is outside of the scope of this forum, and it is most likely a Microsoft issue, here goes nonetheless.  I did not look up your issue or said solutions, but what you should try, is retrieve your Windows CD/DVD.

What you should try is a "system file checker". 

From a command prompt, with the CD/DVD in the drive type the following:

"sfc /scannow"  It might take a bit of time, depending on your installation and may require you to reinstall some updates, as this will restore original forms of the DLLs to your system which are required for functioanlity.

Technically, the problem description above indictes that the "Internet Protocol Routing Manager Dynamic Link Library" has some invalid or rewritten entries and thus cannot perform the way it is expected to and or is calling files/applications that no longer exist or have moved.

It is alot faster than rebuilding the whole system.

I run "sfc /scannow" and reboot the server, but this is does not help for me. :(

Have you tried to go to your Server Components and uninstall and than reinstall RRAS?

How can i uninsatall and reinstall RRAS at Windows Server 2003? It is not available like some component. I try to run windows repair, but no luck.

Any suggesion?

Sorry about the late response, was away for Easter Weekend.

Go to Start -> Programs -> Administrative Tools -> Manage this Server
At the TOP of the page, above "Sile Server" you will find a link to: "Add or remove a Role".  Click it!

Configure your server wizard pops up.
Go to Next and a list will appear.

Find "Remote Access / VPN server", highlight and click next to Install/Uninstall.

If need be, because of "uninstall" rinse and repeat to install.

Reinstalling RRAS does not solve this issue.

Any suggesion?

may be problem is in uninstallation of SEP - symantec was never able to uninstall completely, and some trash still exist in system..
