I have an issue whereby I have a web application installed on one of my Windows Server 2003 virtual machines that has a database held on a local copy of SQL Express 2005.

This has been working fine - I installed the application find and it created the database in SQL, and the software has been operating fine since.

It has just stopped working as a result of me troubleshooting another part of it, but here's the wierd thing - the thing that has broken it is DISABLING the Windows firewall service on my local machine. It is a Windows 7 machine if that makes a difference.

I had the firewall turned off anyway but I know that it can still sometimes affect traffice. Does anyone know what could have caused this problem? The application communicates with the SQL server on port 1433.

Thanks in advance!

What VM software are you using and what kind of networking is it configured for? – squillman Jun 30 '11 at 14:20
So you are saying that disabling the firewall on your Windows 7 workstation has broken the app which runs on a separate Windows 2003 server? Is the VM running within your Windows 7 workstation? – mrdenny Jun 30 '11 at 20:58
Thanks for your replies. I have taken that VM back to a different snapshot and it is now working. Wierd problem though, the VM was running locally. – 5lovak Aug 19 '11 at 9:20
