gethostbyname() calls fail after installation

Greetings to everyone.

I have just installed the latest version of comodo firewall (3.13.121240.574) on windows xp x64 and I allowed every alert message that popped up (most of them regarding nod32 engine and kernel).
Firewall’s and Defense+'s security level were automatically set to Safe Mode.
Yet all gethostbyname() calls fail after installation (for example of browsers and of other applications. In one log of a specific application (a vpn ssh client) I get gethostbyname() call failed: windows error 11004.

Does anyone have any idea how to remedy that ???

Thanks to everyone for your time and help
