visual studio port and firewall interference

visual studio (vwd) keeps saying “unable to launch because the port is in use” no matter what port / whether auto-assign is true. netstat / telnet dont show anything either.

explains that a firewall update can make things go awry

On investigating I found it to be related to the Eset personal security (guessing a recent update messed something up). To solve it I excluded VS2008 from the active browser filtering – this is in: setup -> advanced firewall setup -> antivirus & anti spyware -> web access protection -> HTTP -> webbrowsers

Deselecting vsdev in here fixed the problem – interestingly enough disabling the firewall and antivirus / antispyware did not solve the issue, so it is worth looking for a similar setting if you are running different security software
