Hi Tracy!

Thanks for reply but your solution doesn't solve the problem - the firewall is deactivated.

>You can either disable the windows builtin firewall which is fully enabled by default after installing SP2 or right click the program, go to properties and in the security beside it there is an option to unblock the program, click apply and then you shouldn't be given a Security Warning dialog.
>You can also do it by clicking on start, control panel, windows firewall, click on the exceptions tab and click on the add tab. Select the app from the list (you can browse to it if you have to) that you want to unblock and then click OK.

>>First of all a 'Security Warning' appears showing a message about '... unknown publisher...'.
>>It's possible to prevent this warning by filling out the 'project info' in foxpro - after this everything works fine.

>>BUT when we're trying to run this application on a network-drive which is connected via the IP-address and not via the servername the 'Security Warning' again appears - the project info is filled correct.

>>Is it possible to get rid of this problem (without uninstalling SP2 ;-)?

>>Thanks for any help!
