XP SP2 Firewall and UNC

After the install of SP2 on Windows XP Pro, is there a way to configure an exception in the Internet Connection Firewall to allow access to the Admin Share. I use UNC a lot in the following format. I do a Start>Run>\\computername\c$. This allows me to drop shortcuts etc. on client PCs. You can’t do this with the Firewall on. Is there a way to get around it? Thanks in advance.
