DHCP and subnets |
|
|
My company has 4 locations on the east cost. Each location has its own DHCP
scope. When a user from site A visits site B, C or D for the day they can not
access the network until they release and renew their IP address. In most
places this is not a big deal, however our users do not have rights to
release and renew, so I have to have them log on as the local admin as a
workaround.
The Ideal scenario would be to have any user go to any of the 4 locations
without having to release and renew. Is there a way to do this? I have all
2000 servers running AD with layer 3 switches in-between. Any advice is good
advice, so thank you in advance. |

Yes. This is pretty much the way that DHCP works
unless you reboot them.

The RELEASE is not actually necessary. Can you
find a way for them to try the renewal?
Also you can make your leases much shorter, say
slightly less than the normal travel time between
locations. If best travel time is 30 minutes (without
superpowers) then set the lease to 30 minutes.
I once built a service that monitored the sleep events
like Hibernat sleep/wake, Stand-by sleep wake -- I
would give it to you but it is pretty primitive (took
less than an hour I believe.)
It runs a fixed file name in the System32 directory
which could do such.
Any (careful) VC++ programmer who can follow the
services examples in MSDN can build you one.
This works because people will almost always sleep
the machine to travel but these days will not turn it off.
It could also include a probe for the default gateway,
followed by a renewal if not found.
