I have a vista business. ---
It worked fine with internet, vpn, local network and remote desktop.
On 24-th December something has happened on my laptop. [ Could have been a security update ]
If I am in the office, in the private network I can not connect to the internet,
i can ping all server but I can not connect remote desktop connection, to the intranet webservices, exchange server with outlook.
[can you ping your default gateway? verify the default gateway address as well.
make sure that you have the default gateway by running a dos prompt and tying ipconfig /all
that way you can see DNS settings as well as the rest of the needed info.]
If I am at home, I can connect to vpn, and I can connect to the internet but I can not connect (remote)desktop connection, to the intranet webservices, exchange server with outlook.
All windows firewall I have turned off, I have all rights,(permissions)
no changes have happened in the office environment. (microsoft update? or admin push/pull updates?)
Two days before I have uninstalled the Norton Internet Security and installed the Symantec antivirus.
as part of the uninstall norton queries the user if he/she wants to re-enable the windows firewall, just double check this disabled, .. also if you would uninstall symantec antivirus and try www.avast.com home edition,
I recommend it highly, no I dont work for them but I have been using it for 5-6 years now and it never blocks vpn, and its FREE :) also it puts norton to shame!
In the offices I have to use a firewall to connect to the internet, at home I do not. Has had somebody similar problem? [so at home you dont use a router / gateway device that provides NAT?]
if you could also clarify a few things for me,
when you say you use remote connection, do you mean remote desktop connection? port 3389 or a different port?
what model of netscreen firewall does your office use? do you have an IDP device?
if your able to connect to the internet from home, and your using DHCP at both the office and home, the problem would then more than likely reside with the netscreen firewall, it may be blocking your address or may have put you on a block list in general.
tough to tell without more testing and information.
