Virus tcp ip stack

This layer is the handles the physical messaging and media for data transfer. The basic media protocols and standards exist here.

This layer includes the IP packet along with the IP addressing scheme. This is where the "addresses" of supervisory devices are established. This tells your building automation system which supervisory device to send the message to e. This layer creates the TCP reliable connection and communicates data between sessions. The transport layer creates the reliable connection you need when uploading or downloading BAS databases.

This layer creates the connection between data and the application. If you recall from my OSI model article, I mentioned that the OSI model provides a framework from which developers can create standardized computer applications. So from the perspective of a developer, the OSI Model will help standardize the development of the application throughout all steps of the communication process.

This matters to the BAS user because the majority of newer control systems and third party integration are built around web based services. What this means is that when you go to pull data from another device on most modern systems, you are invoking web services calls against internet centric data.

Oh, help, help, help… OMG! My entire business is on this PC?! There has to be another solution. For real? I would definitely try an above board NIC before I did a wipe and reinstall. Just be sure to disable the on-board NIC after you install the new one. Good luck! You are so not going to believe this…. I was running a print job on one printer, started one on another, and turned on my heat press, causing me to trip the breaker in my office. I turn everything back on.

Any explanations? Incidentally, my power does go out from time to time. Can you recommend a good surge protector, maybe one with a battery backup? So, it sounds like the NIC card took a surge.
