9.x clients can't access Policy Manager 9 and 10 on the 2008 R2 or 2003 R2 SP2 Server when Windows Firewall is on. 80 and 8080 ports are open.
What needs to be done?
Check http://www.f-secure.com/en/web/business_global/support/article/kba/15276 Step 5 in the solution should prove useful. Windows 2003
Open properties for your "Local Area Connection" > Advanced > Windows Firewall > Settings > Exceptions > "Add Port" and so forth.From "Change Scope", select your subnet(s) for which the rule shall apply.
Are you able to "see" the F-Secure Policy Manager by IE (http) from the client ?
You know, the page where you can download the admin.pub-key !!
If not, reconfigure the Windows firewall on the PM, so you can !!
