I have a netgear DSL modem which has hardcoded into it a domain name "netgear.com". When I run IPCONFIG /all I see that the domain name from the modem is showing up in the "Connection-specific DNS Suffix:" field and the "DNS Suffix Search List. . . . . . :" field as "netgear.com". The "netgear.com" info is also used in the "Tunnel adapter isatap.netgear.com:. Here is the rest of the adapters info:

The internet has been a little slower and I occasionally get DNS errors, but in general things are OK. Do I need to be concerned about the "netgear.com" entry? What would you recommend?

the only real effect that you're likely to see from having 'netgear.com' in the suffix search list is as follows:
if you type http://www.microsoft.com or www.microsoft.com or Microsoft.com in your browser you will be taken to www.microsoft.com
if you type in Microsoft then it will likely try http://microsoft and http://microsoft.netgear.com before either returning a 404 (page not found) or dropping you into your search engine
I doubt there are any malicious pages at *.netgear.com so you're probably fine ignoring it. Ideally you'd take a look at your internet router and remove it though.
as for the ISATAP piece, that's a special windows adaptor that lets you tunnel IPv6 through a IPv4 connection. You could disable IPv6, which would get rid of this adaptor, and you'd probably not miss it at this stage. There isn't really any point in disabling it though - and at some point IPv6 might actually become relevant so you're safe to ignore it.
