Thanks for the advice Meldrew. After trying a number of fixes I started to believe the anti-virus software Kapersky was causing the issue, I disabled it but still no luck. I then found out from the Kapersky website that it indeed had caused the issue:
"On Friday, October 25, 2013, Kaspersky Lab has released anti-virus databases, which was mistakenly added detection system file tcpip.sys. This anti-virus databases detected as a malicious file tcpip.sys in Kaspersky Anti-Virus 6.0 for Windows
Workstations running under Windows 7 Service Pack 1 (32-bit), put the file in Quarantine and delete the registry keys that refer to the file."
They have provided a fix, which can be found at : False detection on file tcpip.sys at October 25, 2013
I applied the fix and the issue had been resolved.
