Re: SQL Server 2005 Connection problem 80 80

I compared my computer with the computer which can connect.
I discovered that TCP/IP DNS Address in mine is set to a number, where in the other computer is set to be obtained automotically. And when i changed it to be obtained automatically it returned back again after click OK button and reOpened the dialog.

Is this a virus , or what?
Please help.
If the thread now should be in another place , please administrators select the suitable section for it.

Thanks alot

HI All
Thanks alot for your time,
I discovered the problem .
The trojan changes the DNS to a certain number. I got the removal -Malwarebytes' Anti-Malware - and changed back my DNS.
All work great now.
