Re: Unable to obtain a server assigned IP address

Tech-Archive recommends: Fix windows errors by optimizing your registry

Ok, I see that I can still get an address from the DHCP server on
192.168.100.254 when I have the static 169.xxx address set, so I guess this
necessarily means that the 169.xxx is for a different NIC, although it was
anything but apparent.

What about the DHCP registry flag per question below?

Also any clarification about the nics in the device and access to set static
or dynamic IP's for the various interfaces, and what they are, would be much
appreciated.

Sorry for talking past you, just to save you answering something I could
find out for myself.

best,
dan

Thanks *very* much for the swift response. Well the wifi router won't be on
the same subnet since most of the nat routers (including mine, a dlink)
use192.168.xxx or 10.xxx for the hosts since these are "off net". Also, one
has no control of the subnet when going to another location and using the
routers there.

For specificity, I recently got an MDA aka HTC Wizard.

My confusion is that I don't know what interface I am assigning the static
IP to. In the connections panel three adapters are listed: Remote-NDIS
HOst, NE2000 Compatible Driver, and SDIO WLAN Wireless Adapter. To fess up,
I don't know what Remote-NDIS Host means. However when looking in the
Network adaptors menu under "wlan", this seems to be the interface that it is
using, not the SDIO thingie.

If ActiveSync routing is being sone via some kind of proxy (the AKU thing,
whatever that is?), then why does the wlan interface matter?

I guess I am not clear on what is being set to 169.xxxx or why setting it
to this value makes the OS find a connection.

I don't use or subscribe to GPRS so I haven't experimented with that
interface.

I don't know whether others have the same points of confusion, I suspect
they may either know more, or less, or just want a recipe.

Hope this helps focus the confusion (and hopefully remove some). It seems
that random notes on this error message, and the 169.xxx fix are posted all
over the net, but without explanation. Your posting was the only one I
spotted that seemed to know what they were talking about (fundamentals
wise)!!!

Also, what does the DHCP flag in the registry do? One poster suggested that
the ppc was trying to act as a DHCP server when this flag was on (seems
unlikely, right?). I was reluctant to turn it off because of the above
concern (e.g. the ppc needs to acquire a DHCP address from a router when used
"on the road")--- right? or is it (seems absurd) a flag to allow the ppc to
be a DHCP server?

Many thanks again for you time and help.

Best regards,
dan

If the WiFi router is still on the same subnet, it shouldn't care.
Obviously, if you have a static IP set for your wireless device and then you
change the subnet part of the router's IP address, then it's not going to
work, but it doesn't care if its users got their IP addresses from it via
DHCP or whether they are statically allocated.

Yes, each adapter must have its own IP address and there is no need for them
to have *any* relationship to each other. The WiFi adapter might be
172.16.0.127, while the GPRS adapter might have 221.147.2.77 (or whatever;
they're just random numbers, as far as you know). The only effect that one
has on the other is that packets might be routed via one adapter or the
other because of which network they are configured to be connected to or
which interface is lower-cost (usually this equates to "faster").

In any case, though, when communicating via ActiveSync to the Internet,
routing is being done by the desktop PC on which ActiveSync is running.
It's routing, really it's proxying, packets from the Pocket PC to whatever
server it's trying to talk to.

I think you may have missed the point. Some ppc's have multiple nics, e.g.
the usb for activesync, wifi, bluetooth etc.

If one freezes the IP of the subnet, as you describe, then what happens
when
trying to access the (inter)net through a wifi router which is running a
DHCP
server? Is the ppc capable of different ip's for each of its interfaces?
If
that is so, then how come the NDIS seems to be generically associated with
connections?

Thanks in advance for your response.

You lost me. The IP is just the IP of your local device. It neither
enables nor prevents Internet access. The ActiveSync program running on
the
connected PC is responsible for forwarding the network traffic to Web
servers, etc. That is, the router configuration of the *PC* determines
how
the Internet is accessed.

This is on the device that you see the message or on the PC? If the
device,
open the Control Panel | Connections | Network Cards applet and tap on
the
Remote-NDIS Host item. If Use server assigned IP address is selected,
change to selecting Use specific IP address and set the address fields
to:

169.254.2.1
