I could open hotmail till today afternoon.. now I cant. but I doubt it must have something to do with MTNL

Use a tool like nslookup to first verify if your DNS resolution is happening correctly. If its not happening, use an alternate DNS server like 202.54.1.18If DNS resolution is successful, try and telnet to citibank.co.in port 80 to check connectivity. If this doesnt work, either the website is down, or your firewall is blocking traffic.

this seems 2 b a definite problem (mite b intermittent) with the MTNL DNS servers. when u r connected 2 office via VPN u use ur office's DNS servers (as u told) & these DNS servers internally query d Service Providers DNS servers from whom ur office has taken net connection. I believe ur office net connection is not from MTNL. Anyways 202.138.96.2 & 202.138.103.100 r d DNS servers for reliance which seem 2 respond properly. Try changing ur Internet connection settings 2 use these servers & chk whether it works. Anyways try telnetting 2 port 53 of d MTNL DNS server whenever u rcv this problem. If d DNS server is working perfectly u shud get a blinking cursor else u'll get a connection timeout msg.
