Cisco PIX 501 error "regular translation creation failed for protocol 47"

A user here is trying to connect to an external VPN server, using the WinXP Pro VPN client. He can connect from his home but not the office network, so I suspected the settings on the Cisco PIX 501 firewall. The syslog has this error from the connection attempt:
Nov 15 2006 11:36:06: %PIX-3-305006: regular translation creation failed for protocol 47 src inside:10.2.1.105 dst outside:66.117.174.105

Any suggestions? Both our usual Cisco config people are uncontactable and it's fallen to me to resolve this urgently. I'm naive about this so I expect I have missed a lot of important info.

If your PIX is running 6.3 series software, login to the PIX via telnet, SSH, or direct console, & add a "fixup" command, eg:
pix# conf t
pix(config)# fixup proto pptp 1723
pix(config)# exit
pix# write mem
