Windows SharePoint service 3.0 wss3 URL ing problem, almost deprecated the website

Wss3 is newly installed in the company. The interface is very beautiful, but it is very slow and consumes MB of memory.

After the installation is performed by default, the host name will be bound, that is, the host name will be automatically redirected when the IP address accesses the website. If it is not in the same domain, the computers in the working group cannot resolve the domain name, which is troublesome.
Solution:
Control Panel-> Administrative Tools-> SharePoint 3.0 Management Center-> operations->Backup access ing-> Add an internal URL and specify an IP address in it.

My original practice was to directly edit the original URL and change the computer name to IP address. The result was accidentally changed to an incorrect IP address... the nightmare started.
Obviously, SPS do not judge the IP address validity. How can I open the Management Center? After I log on, I cannot access it after a long wait.

It is useless to change the hosts domain name resolution.
Later, many command line tools were found in the c: \ Program Files \ common files \ microsoft shared \ Web Server Extensions \ 12 \ bin directory. Finally, add addalternatedomain/extendvs/extendsvsinwebfarm /....
Finally, the admin port, stsadm-O setadminport-port 3800, is changed. Ha, finally got live. SPS automatically add domain name-based old port and New Port ing...

The first time I contacted Sharepoint, I never found a database. I hope you can give me some advice.

In addition, you can access the entire website anonymously Without Having to Log On each time.
