One of my friends was granted a dial-back internet service from his company, and asked me to configure his PC corrospondingly. I configured his DNS server, TCP/IP service, the dial-up program, and IE. everything worked fine until I restarted the computer.
Some of the proxy settings in the IE were change, in the HTTP proxy feild I find a ranom letters and in the port feild the number 4444.
I tried several times but the same thing happened again.
Can you help ?
