504 Gateway Timeout

For quite few days I’m experiencing a different situation while trying to access Yahoo groups.

I’m using NT4.0 with IE6.0. For quite many years, I never faced any problem with IE5.5. Couple of weeks back I installed IE6.0. From that day onwards or after that, I couldn’t able to open Yahoo groups. I tried with netscape4.75 under NT4.0 & Windows XP in another machine,the same problem continues.

Can any one help me in this regard.

Pls send u r replies @ srglan@yahoo.com
