Hello,

currently i am facing following issues on windows 2003 server -

1- In hijackthis logs found error - Broken Internet access because of LSP provider 'c:\documents and settings\administrator\windows\system32\mswsock.dl l' missing

2- we are not able to browse any website from problem server or not able to run
windows update (In short no internet connection)
But all other websites on server is working fine. Also I did nslookup to
google.com or other websites and it work fine.

3-start >> run>> \\another server ip in same network = Do not work ro not able to
connect another server.
But after reboot if we try same command it work fine and ask for login.

4-Also I did try to RDP from problem server to another server --- DO NOT work ,
after reboot of problem server it may work

UPDATE - After reboot of problem server everything work fine for 2 days and again all problem mentioned above start.

mswsock.dll is part of microsofts winsock protocol, it may be worth un-installling the network components of server 2003/rebooting and re-installing them to see if this corrects the problem. This problem may have been caused by spyware or even a microsoft update. Also worth checking you have the latest service pack on server.

this tool has helped me out a few times when the server is complaining of missing .dll files
sfc /SCANNOW is a system file checker - it checks protected files and their versions and repalces them if theres a problem from the dllcache folder under system32, make sure you have the server 2003 instalation files to hand as theres a good chance it will ask for them.

Have you tried running a chkdsk?

If all else fails you could try running an implace repair of server 2003 over the top as a last resort, before restoring from a backup/or rebuilding

Hello,

Please check following steps and let us know result:

1) Ping your Default Gateway
2) Ping Primary DNS Server
3) User following command "telnet www.google.com 80"

This can be issue with port blocking or something.

I agree. It looks like port blocking because the OP can do nslookup external domains.

2- we are not able to browse any website from problem server or not able to run
windows update (In short no internet connection)
But all other websites on server is working fine. Also I did nslookup to
google.com or other websites and it work fine

Ans . Its a DNS issue . In your LAN , in TCP/IP properties , please check the DNS servers . Or you can use google DNS servers .
8.8.8.8
8.8.4.4

-start >> run>> \\another server ip in same network = Do not work ro not able to
connect another server.
But after reboot if we try same command it work fine and ask for login.

Ans . PLease check if , the computer browser , server and workstation services are running . If any one is stopped you cannot use network sharing
