I've set up 2 XPs with internet connection sharing and the server connected to the internet via ADSL. Both systems work ok except that : The client can not install ICQ; The client can not ping or connect to some web sites like www.icq.com, www.ibm.com, etc. The server can connect to these sites w/o any problem. The DNS setting on the client is ok and finds out the correct IP. The client can connect to many other sites without problems. Could anybody tell me what the problem might be ?
