I compiled and installed the sample driver that Thomas Divine published last year. However, when I tried to open the driver from the user app, I get an invalid...
Did you build the driver using the Windows 2000 Build Environment of the Windows Server 2003 DDK? If not, then build it under the Windows 2000 Build ...
I am trying to develop a Ndis driver for encryption and am currently having trouble decrypting an inbound payload then strip off any padding and resize the...
Unfortunately, Robert, the NDIS packet/buffer/VM that is passed to you in your receive handlers is effectively read-only. You cannot modify the receive packet...
Hi, I try to develop open source kernel level traffic control utility (or traffic shaper) and its main part - NDIS driver. I decided to implement packet ...
Hi, I'm currently developing a software project that consists mainly of one NDIS Intermediate driver. Now, the challenge I'm approaching to is the following: I...
Either one is a bad idea, and your premise of do it before login represents a flawed design. You are assuming a PC with a single user, with a standard ...
That's all perfectly true - obviously I didn't make myself clear enough. The configuration changements that shall be selectable by the user are settings you'll...
Well you still have a problem. First understand what DriverStudio does is a complete hack, that does destabilize some systems to the point of destruction, so...
Well, if it's not possible to solve the problem that way, what possibilities do I have? Would a GINA dll solve the problem? Which technology would be able to...
Peter, There really isn't a good solution. Note, this really isn't something Windows provides for, or is expected. GINA will not work since you do not want...
Hi, just some question: The PUSH flag in the tcpheader indicates, that the data should be passed to the application at once - so it should only appear together...
... I am not an expert on this. However, it seems to me that: 1.) The PUSH bit says that the data I am sending in this packet should be presented to the...
a) Enable driver verifier for your driver. b) Simplify the stack -- take out, for instance, QoS packet scheduler, etc. What OS are you testing on? If this is...
In your MiniportSendPackets routine take a careful look at the acceptable IRQL of functions that you are calling. The DDK usually includes a statement of the...
a sender and 2 remote nodes are connected on a ring. what is protocol stack implementation when sender sends to 255.255.255.255? I believe that sender sends to...
Thomas, Thanks for your insight. I followed your suggestions, and I was able to get the passthru sample driver running. - Pascal ... of the ... 2000 Build ... ...
Things are slightly different than Thomas indicated. The PUSH (also called PSH) bit indicates that there is data present in the packet after the TCP header....

Mike, Thanks for taking the time to give some insight into this. Thomas F. Divine...
... No, DefendTek is a Firewall. At the TDI level firewall and a content filter both inspect the information that is exchanged between the local host and...
Hello, I want to write a virtual network device on Win 2000/XP like a virtual device of the software VMWARE. I need to capture packets from and to all networks...
I believe that Thomas was nearer the mark about the PSH bit as you can actually have data packets with data in and no PSH bit set. The PSH bit indictates that...
Hi again, thanks a lot for all your help. I turned on verifier, but that didn't unhide the culprit (by the way, I'm developing for Win2k3 server). But then I...
... Not exactly. The DDK documentation says: "The MiniportSendPackets function of a deserialized miniport driver can be called at any IRQL <= DISPATCH_LEVEL" ...
