Hi,

I have been having a computer network problem for the past one year now.  The problem is, my computer network hangs ups from time to time and this is owed to the domain or main file server. I already checked the utilities of AD and DNS and have also tried DENS error events like 4015 and 4004 but it turns out to be ok. I think the server is also having a hard time. What advice can you offer me?   

We’re using PEM 7.3. I would like to edit the URL notification of end-user and change it to an external IP of our mail server instead of the internal DNS. How would I do that?

I want to know about the reading sequence of SQL server that, does a SQL server always read the data from the hard drive put it into the Ram and then work on it?For Example: you have just done a very complex join and after that you will getting data from number of tables (the material is unsorted), then you do an order by to sort it,Does all that data have to be read first in the RAM ,and then SQL does sorting?if YES then what if there are million of rows? 

Hi,

I want to configure a network. I want to connect different types of devices. But I don’t know what kind of connection (crossover or straight) is used for different devices. Such as computer to hub, computer to switch, computer to router, computer to computer etc.

If you are into a business you always consider your total cost of ownership (TCO) for your investment. Now, if you have about 50 computers, why then buy  a server which is very costly when you can just connect all your computers into 1 personal computer where you can just load a server software? 

What are the technical components of 3-Tier Client / Server Architecture and how can I implement it. What is the difference between a 2-Tier Client / Server Architecture (2 Level) and a 3-Tier Client/Server Architecture (3 Level)? What are the advantages and disadvantages of each architecture?

Thank You!

Hi Experts,

I was trying to compress or zip several files into 1 file when this error message popped up on my screen (please see below). I have checked the drive where the file would be created and it seemed that it had enough space. 

Any suggestions on what to do next?

Compressed (zipped) Folders Errors

There is not enough space on the drive to perform this operation.

I have files in my computer contain a lot of data. I tried recently to delete some of them but there  is a problem that some I could delete and another I couldn’t. I tried to use unlocker but problem is the same. So please anyone tell me what is the problem and how to fix it.

hi all,

Workstation slow access to mapped drive?

Can anyone explain a solution

regards

My friend gave me this link and I want to view it. He said that site contains the information I needed to know about a certain something. I just want to view it but then this error keeps telling me that can’t view it. Is it that the server is only down for a couple of minutes or so? I need help on this thing.

Connect to Server

Cannot connect to 192.168.3.40.
