Error message regarding DNS

Hello forum and Merry Christmas to all.

I'm having an issue with a software I'm trying to install which is not Microsoft related (but it could be)
its not installing correctly. Im a bit frustrated because I'm stuck with no progress. I recently got a reply from the forum admin giving me some insight, but I dont know if he is 100% with his solution. So anyone who can shed some light is highly appreciated, Id like your opinion to his reply/solution if this is the case.

Hi Yard dog!

I dont think this is the answer to my problem. My internet is running fine. Im just trying to install and run my own server on my desktop using serverpress. Thats where the trouble begins. The link you posted seems so complicated for my issue... Did you read my post in the Serverpress forums? This is not an internet connection from what the admin has stated.

Okay, do this please. run SFC 3 times to make sure your files are in order. seems something is missing: SFC /SCANNOW Command - System File Checker

Hi Graphomet,

Firstly the Manual change of DNS servers mentioned is I believe a "red Herring" - All this is doing is setting the DNS server, used for internet Lookups, from the normal (ISP Provided), to Google public servers, (not a bad thing in itself, but not really valid here).

The error message you are getting may be more important, It is caused I believe by a permissions issue, Windows 7 protects the Hosts file quite vigorously from changes, (it is a known target for malware and can cause major issues if compromised.). In order to access and change the contents of the Hosts file, you must be running with administrator privilege, I suggest that you run the software by right clicking the executable and "Run as Administrator" if you are already doing this it may be necessary to manually add any entries you need to, to the host file, (run notepad as administrator, and open the file directly).

Check the software documentation, for the details of the additions to the hosts file that are required, The host file works as a local manual store for fixed DNS entries, so an error here will lead to issues with the running of any local DNS server

Hi Barman.

Im going to give that a go too, to run as administrator and see if I might just be lucky. But do I have to uninstall the software and reinstall the software?

Right now Im doing what yard dog suggested to try the: sfc /scannow. Its my 3rd time and so far nothing comes up.

Thank you.

If you get No integrity violations on 3rd time.. then do as our moderator suggested. And btw.. hope you always run as Admin. even if on non admin account.

Ok I located my host file in my drivers etc folder and opened it up with notepad ++ the softwares domain is not located in there in order for it to be blocked. Am I thinking correct so far? and also regarding the message I am getting when the software is running:

Error-unable to write and update
“c\Windows\system32\drivers\etc\host”.

whats it got to do with me trying to connect to the internet server, and updating the host? is this a common problem, or is my system in away misconfigurated. The fact that sometimes I get the BSOD does it play a role to all this issue?

The hosts file is an old system file that is still used by windows - It holds information on URL to IP addresses that windows can fall back on if there is no access to a DNS server either on the Local network or the Internet.

When looking for an address for a URL, windows checks the hosts file before any other location so as you have mentioned this is often used to "block" a particular address, by redirecting the URL to a null IP Address, (normally LocalHost at 127.0.0.1).

However, the original use for the hosts file was to direct address queries on smaller systems where there is a local network but no DNS server. looking at the application you are trying to install/Use, I am assuming that there needs to be an entry made in the hosts file for the "fake" server that will be used for testing.

this would be something like

www.server.dev 127.0.0.1

there may also be a requirement to allocate a port number which is set by following the ip ddress by :nn where nn is the port required so the entry above to access the normal web port, port 80, would be ....

www.server.dev 127.0.0.1:80

you would have to check with the software documentation or the developer forum as to exactly what is needed to be added to the hosts file manually
