Sorry, that was the day before Thanksgiving and I didn't check back promptly. I don't have the log entry in front of me, but it was outgoing, and I &quot;think&quot; I remember it being UDP but I'm not sure now. It hasn't happened again, I was curious about the destination. What you've pointed out is true, it was just peculiar so I thought I'd see if anyone knew exactly what that was. I'm satisfied with your response, I don't believe I'm going to get any others either. I'll award the points, please feel free to add any other info you wish.<br />
<br />
Thanks.

My personal firewall just popped up a warning for MSDTC on port 1388. <br />
<br />
I looked it up and all I can find is &quot;Objective Solutions DataBase Cache&quot; for that port number. &nbsp;<br />
<br />
I have no idea, does anyone know what Objective Solutions is? I don't know of anything installed on my machine that would cause this but who knows.<br />
<br />
I was in Internet Explorer at the time, and telnet was running to my router. That's about it.

What is Objective Solutions DataBase Cache, port 1388?

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
