HOSTS file ignored. IE virus?

[Tim Jowers]

Summary:

IE doe snot use HOST file apparently when host name has over 2 dots.

Completely"

1. update HOSTS like
10.49.32.2 common.t3.tms.com

2. Save and
ipconfig /flushdns

3. ping common.t3.tms.com
Pinging common.t3.tms.com [10.49.32.2] with 32 bytes of data:

Reply from 10.49.32.2: bytes=32 time<1ms TTL=128

4. Try to navigate to URL http://10.49.32.2/xmlbeans/vehicle.xsd
works

5. Try to navigate to URL
http://common.t3.tms.com/xmlbeans/vehicle.xsd
fails FAILS FAILS FAILS FAILS

6. Try HTTP GET with telnet
telnet common.t3.tms.com 80
GET /xmlbeans/vehicle.xsd HTTP1.1

returns web page

7. Tried workarounds like clearing IE cache, clearing history,
rebooting. Also like LMHOSTS and nbtstat -R.


Ideas? Why do I spend 75% of my time on GOTCHAs?

Maybe a virus like in the reference above that reworks hosts file
lookup? Maybe some issue with IE resolving each domain before the
subdomain and that not working? Maybe some way the DNS is setup here
that HOSTS is not looked up first? ???

Restart DNS client service and post 'ipconfig /displaydns' output. Do you
have local firewall?
