In general, VPN users are connected to the VPN server is to enter the password, if so, in some public places when the password is likely to cause leakage of passwords, resulting in unnecessary losses. Password Authentication protocol Although the hardware requirements are not as high as the Challenge Handshake protocol, however, in terms of security, it is still a distance from the challenge handshake agreement. The specific authentication protocol to be used, the user should be judged according

When the Microsoft firewall service starts, it exposes the ifwxfirewall interface, which provides access to Firewall service functions.
An application filter must include a COM object that implements the ifwxfilter interface. this object is called the filter object. when the Firewall service starts, it creates an instance of the filter object for each application filter that is installed on the ISA Server computer and enabled. the Firewall Service i

With these two problems solved, the rest of the work is simple.
It can also be explained from the above that the FTP server for IIS cannot be published from the intranet because IIS has no option to choose the range of PASV ports or to return the addresses of the ISA extranet. And serv-u These two can be satisfied. Of course, there may also be a way to solve these two problems with IIS on the Microsoft Web site.

refresh of the Bootblock (boot module) in the motherboard BIOS. Only after using the/SB parameter when upgrading the BIOS can we recover the pre-upgrade BIOS data with an bootblock that is not compromised, or it may not be recoverable. Even if you have an emergency recovery disk in your hand, it will not work.
All we need to do is start the system with a copy of the boot disk with Awdflash.exe and *.bin (preferably a Autoexec.bat file with "Awdflash
motherboards are more critical of memory, and once plugged into the motherboard can not recognize the memory, the motherboard will not be able to start, and even some motherboards do not give you any fault prompts (tweet). Of course, sometimes in order to expand the memory to improve the performance of the system, the result of inserting different brands, types of memory will also lead to the emergence of

Because the registers of DMAC are configured in the I/O port space, reading and writing 8237 DMAC is platform-related. For x86 platforms, Linux implements read and write operations on two 8237 DMAC instances in the include/asm-i3
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
The last week, I have a lot of local area network problems, mainly for, open a Web page, sometimes directly open, sometimes can not, need to press F5 refresh the page, refresh a few times on the open.
Found on the internet for a long time also did not find a solution, thought to be a netcom problem, with good Cisco2600, do NAT Internet, replace the next couple of Win2003sp2 + ISA2004SP2, found the network extremely normal!
This concludes that the problem appears on the WIN2003SP2 + isa2004sp
