J'ai a recurring DNS problem that has been plaguing our users occasionally causing leur laptops to appended our companies domain to le end of tous DNS queries. The problem seulement occurs quand users are offsite et it appears to be fairly random. It will work one day et alors out of le blue it will show le invalid entry. This affects mostly Windows XP users mais has recently been seen on Vista as well. Here is an example using nslookup.
C:\Users\Username>nslookup www.yahoo.com
Server: Linksys
Address: 192.168.0.1
Non-authoritative answer:
Name: www.yahoo.com.EXAMPLE.COM
Address: 192.0.2.99
J'ai replaced le IP address that is reported avec a placeholder mais I can tell you that what it returns is le par défaut *. entry on our Network Solutions configuration. Since obviously www.yahoo.com.EXAMPLE.COM ne exist this makes sense. Je crois le user's internal equipment is functioning properly. Internally we run a Windows 2k3 Active Directory w/ Windows based DHCP et DNS servers. Eventually le problem resolves itself usually over a couple of hours ou a number of reboots.
Has anyone seen this behavior before?
