DCOM With Limited Ports

Dec 1, 2011

We need to put a firewall in between our servers and a couple of clients. To do this we need to limit the number DCOM ports available so that we know what ports to open on the firewall.The question I have is do we need to limit the number of ports on all the machines inside the firewall as well as outside. This would cause an issue as we have lots of machines which would need to be modified.If DCOM has the intelligence to negotiate on port 135 which port is available on both machines which need to communicate, we will only need to modify the 2 machines on the outside of the firewall.

Schedule Task - Error: Server Did Not Register With DCOM

Jan 20, 2010

I have an old Visual Basic 6.0 application. The program was compiled and ran as a schedule task. It creates the pdf files. When I look at the event viewer. It gives me this error message. The server {85DE1C45-2C66-101B-B02E-04021C009402} did not register with DCOM within the required timeout. The application id refers to adobe file. The schedule task never runs. This above error message showed up on the event viewer. 

If I run the application by itself, it creates the pdf files with no problem. Any idea with this issue. I did a look up on this error. There is no solution for this issue that I came across on the web.

2. Which technology would allow me quicker understanding?
3. Is there any specific sequence to this learning?

I understand the questions might be stupid; however, this would help me concentrate on one instead of all over the place and archiving nothing.

Aid In A Technology Classroom At A Middle School?

Nov 10, 2009

I am an aid in a technology classroom at a middle school. They have 12 computers that must be logged into everyday. The teacher has given me the password to log in the computers for the students, because he doesn't want them to know it. The teacher's computer is linked to the other 12. I was wondering if it is possible to develop a program that has a list of the 12 computers with 2 fields, one for user name and password. These for each computer. You would enter the username and password and it would log in the computer. This would be done from the teacher's computer. It would make it a lot easier than having to go around and log in those computers. [URL]..

Which Database Technology To Use Making A Dictionary

Mar 3, 2011

I am creating a dictionary software in Visual studio 2010 (vb). I've already done one in which i used SQL server express 2008 to hold the data. But users find it very annoying to download SQL server (of 58 MB) before installing the software.I am definitely not using SQL this time. But I don't know which database technology does not need a prerequisite software. I guess ADO.NET will not be favorable too. So can anybody suggest me which one to select this time, so that the users can use my software having just the .NET framework 4.0 and nothing else?
