Why is my laptop trying to request wpad.holidayinnexpress.guest

q: A customer's laptop was making odd URL requests to the router that all ended in holidayinnexpress.guest.  What is causing this.
a: Recently the customer stayed at a Holiday Inn Express and used their connections for internet.  Holiday Inn added a DNS suffix entry in the advanced TCP/IP settings of the laptop.  Simply remove this. 

To resolve this (in Windows 7)

1. Right click the network icon (down by the clock)
2. Click "Open Network and Sharing Center"
3. Right click on your "Local Area Connection"
4. Click Properties
5. Select "Internet Protocol Version 4" and click Properties
6. At the bottom of the Internet Protocol Version 4 (TCP/IPv4) Properties window click Advanced
7. Click the DNS Tab at the top
8. Select holidayinnexpress.guest under "Append these DNS suffixes (in order):"
9. Click Remove.
10. Click OK, OK, OK
