        I using the below service for adding contacts to the Exchange server 
2000 which is running on Windows 2000 server. My problem is that I able to do 
it using this service from Visual Basic. But when I add an Contact for a user 
from WAP it is not adding and taking long time and after some time giving an 
message saying that 'Network not available' in the UP Simulator. And even when 
I test the same page in IE, there is no response. The funny thing here is that 
it is working from VB Source code but not from WAP or in IE. Can any one please 
help me out in solving this issue.
