Recently, the ISA Server encountered a solution that failed to open the webpage (error code 64 error ).

In the last week, lan problems occur frequently, mainly because you can open a webpage directly or press F5 to refresh the webpage several times.

I haven't found a solution after I searched for N on the Internet for a long time. I thought it was a Netcom problem. I configured cisco2600 and used Nat to access the Internet. After I replaced win2003sp2 + isa2004sp2, I found that the Network was extremely normal!

It is determined that the problem occurs on win2003sp2 + isa2004sp2 and isa2004 is patched with SP3. The problem remains the same. After isa2004 is deleted and isa2006 is installed, the problem remains the same.

In desperation, I opened the log monitoring function of isa2006 and found that the problem occurred on the Web proxy filter. I used isa2006 Enterprise Edition. I cannot disable the web proxy filter, so I have to think about it again.

Open firewall policy> toolbox> new protocol open new protocol dialog box, create a TCP 80 outbound protocol, and name it myhttp

Open the firewall policy attribute. In the Protocol, this rule is applied to all outbound protocols except the selected one, and then the built-in HTTP protocol is added.

In this way, even my firewall policy will no longer use the web proxy filter, call the log, monitor for more than n minutes and find no 64 error again. Now the problem is solved!

Using this method will bring security risks to ISA. We recommend that you change the security risks in time when there is a solution!
