i want to know all seting for proxy including server setings

Zubair Ahmad’s “Proxy Server 2.0” (October 1998) is an excellent overview of the product and its security features. I want to comment on a few of the statements in the article and provide additional information for new Proxy Server administrators.
In Security: Server Proxying, the
article states, “To use Exchange in server proxying, you must configure static packet filters and set up authentication.” I think it’s better to say that an administrator must configure static port mappings on the client side (as the Microsoft article “How to Configure Exchange Server with Proxy Server” at http://support.microsoft.com/support/
kb/articles/q181/8/47.asp describes). If
you use this approach, packet filtering settings on the Proxy Server system remain untouched. You can use static packet filters to configure Exchange Server (or other services that use well-known IP port numbers) to work from behind Proxy Server 2.0, but the process doesn’t relate to the server proxying feature.
In Security: Alerting and Logging, the article states, “When your system reaches these [alerting] thresholds, Proxy Server 2.0 can notify you by email (via Simple Network Management Protocol—–SNMP) or pager (if your email product supports paging).” Proxy Server uses Simple Mail Transfer Protocol (SMTP) to send its notifications.
As for VPN support, it’s a feature of Routing and Remote Access Service (RRAS), not Proxy Server. Proxy Server can coexist with (and complement) an RRAS-based Point-to-Point Tunneling Protocol (PPTP) Virtual Private Network (VPN). Read the Microsoft articles “Coexistence of RRAS, Internet Explorer, Option Pack, and Proxy (http://support
.microsoft.com/support/kb/articles/q183/5/37.asp) and “Using PPTP, RRAS, and Proxy Server 2.0 (http://support.microsoft
.com/support/kb/articles/q176/9/24.asp) for details and configuration hints.
In Improved Cache Architecture: CARP, the article notes that “Microsoft developed CARP to overcome the limitations in the Internet Cache Protocol (ICP), which Proxy Server 1.0 uses.”
In fact, Proxy Server 1.0 doesn’t sup-
port ICP or any distributed caching
protocol.

In the article, I meant to say that Proxy Server 2.0 utilizes SNMP for alerts and SMTP for email (mentioned under the Security: Server Proxying topic). CARP overcomes the ICP limitations as I
mentioned; however, Proxy Server 1.0 did not use ICP. Thanks for pointing
that out. My main point in the article was that setting up Exchange with server proxying can be complicated. Please refer to the Microsoft article “How to Configure Exchange or Other SMTP with Proxy Server” (http://support.microsoft.com/
support/kb/articles/q181/4/20.asp) for detailed information about setting up the server proxy feature of Exchange Server. The reason I listed VPN Support as a Proxy Server 2.0 feature is that using Proxy Server 2.0 along with RRAS gives you the ability to use the Internet as a secure VPN. Obviously, VPN requires PPTP, which you install separately from Proxy Server 2.0. I apologize for any confusion the article might have caused.

Zubair Ahmad’s “Proxy Server 2.0” (October 1998) helped me understand Proxy Server 2.0 before I took my MCSE exam. I plan to earn my CNA and MCT certifications this spring, and I’ll use the article for reference in both programs. Keep up the good work!

I’m glad you found the article helpful. You might want to supplement your studies with Windows NT Magazine’s Article Archive CD (http://www.winntmag.com/
archivecd). I use it and recommend it to all my students.
