An external source hacked our Windows 2003 Server via ASP.NET account, installed Proxy Switcher and Proxy Finder. Upon running a malware scan, machine rebooted. Now, TCP/IP settings-->Network Connections details is null; however, TCP/IP properties are accessible and modifiable.
DHCP, DNS, SQL and many other services will NOT start, even manually. When we modify TCP/IP properties, Windows prompts that the server be rebooted upon saving changes (not protocol).
When attempting to repair local connection, receive error: "Windows could not finish repairing the problem because the following action cannot be completed: Failed to query TCP/IP settings of the connection. Cannot proceed."
When attempting to start local services (i.e. DHCP, DNS), receive error 1068.
We have attempted uninstalling the network driver and allowing the OS to auto detect the driver.
