Did you read the documentation for TIdIcmpClient? It says the following:
"Note: For Windows NT, and Windows 2000, administrator privileges are
required to allow TIdICMPClient.Ping to work properly. The command line PING
application does not exhibit this behavior because Microsoft chose to use
undocumented calls in ICMP.DLL and its winsock implementation to get around
the issue. In short: they cheated. Indy does not use ICMP.DLL to maintain
Linux compatibility, and allow use of both Raw sockets and ICMP sockets."
In the case of NT, the following article explains how to turn off the
PRB: RAW Socket Access Denied to Non-Admin Windows NT 4.0 and Windows
In the case of Win2K, there is no way to bypass that restriction, sorry.
If that does not suit your needs, then you will just have to forget about
using TIdIcmpClient and use Microsoft's undocumented Icmp.dll instead.
