Unable to open files on the moss site from the Internet

The moss2007 site was released to the public network through froefront TMG and tested externally. Anonymous Access and login to Windows identity verification are normal, think everything is fine. Yesterday, I uploaded a guide for using an internal email system, which allows foreign branches to download data from the Internet. Who knows that the phone number will be called soon and the file cannot be opened! You have no face. After a careful test for half a day, there is no problem with the Intranet, but the Internet cannot be opened. The 500 Error reported by IE is said to be a friendly HTTP Error message, and such a prompt will be received no matter what the error is, I thought it was irrelevant to blocking high-level characters. I asked in the group today that a brother said that this error of ISA is generally related to blocking high-level characters. I tried to modify the access rules and the result was really a problem!

It can be seen that, for any product of Microsoft, it will always encounter such a difficulty. Although it is not a problem for experts, it is not a problem, but for actual work, if it cannot be solved, it becomes a big problem. Thanks to the enthusiastic friends in the moss group, it is with so many enthusiastic friends that more people are constantly improving!
