Re: Getting around a Proxie?
It probably isn't a proxy that's preventing you using Outlook, POP E-mail and Skype, the admins probably are blocking the ports in the firewall that those apps use. So even if you defeat the proxy, those problems still won't be fixed unless you also are clever enough to run port redirection (which is a nutroll on a Windoze system).
IMHO, the best solution for POP E-mail is to forward from the POP account to a webmail account that supports secure HTTP access (HTTPS). HTTPS almost always is available because it uses port 443, which must be left open or a great many "legitimate" security transactions will fail. That also is why it's preferable to select an anonymous proxy that supports access via HTTPS, i.e.,
https://proxify.com/.
Defeating the proxy, BTW, does not mean you're invisible. You still will leave footprints. If it's an administrator worth his salt, he checks his logs regularly and you will be discovered. If you're lucky, he'll consider it harmless and look the other way. If not, you can expect some measure or retribution up to and including locking out your account.
Oh yeah, you also can defeat a DNS filter by configuring your NIC to use one of the OpenDNS servers, but that presumes you have sufficient credentials to modify the NIC's properties.
Practically anything can be thwarted if they've left you access to command line, which is why it's usually prohibited by GPO.
