Sometimes, no matter how many times you uninstall TCP/IP or Network drivers, your computer refuses to connect properly to the network. Signs usually entail erratic network connectivity, webpages won’t load when first accessed, no ip address is bound to the adapter, etc. The instructions below provide a way to essentially REINSTALL TCP/IP and fix corrupted Winsock registry values. If these steps do not work, the best thing to try is to run a repair using your Windows 2000 CD.

Grant Full mailbox access to Domain Admins and Enterprise Admins in Exchange 2003
One would assume that administrators (Domain Admins and Enterprise Admins) would be allowed to fully control user mailboxes. Unfortunately, this presumption is shown to be incorrect when admins try to add additional mailboxes to their Outlook client. Of course, you can always manually set permissions on a per mailbox basis, but that defeats the purpose of global mailbox management. The cause is due to Microsoft deciding to globally set Deny permissions to Full Mailbox Access (Send As / Receive As) and hide the security tab in which one could edit these permission settings in Exchange System Manager. Fortunately, there is a simple registry fix for this problem.
1.Run regedit
1.Click Start, point to Run, and then type regedit.
2.Add registry key ShowSecurityPage
1.Go to HKEY_Current_UserSoftwareExchangeExAdmin
2.Once you reach the above section of the registry you need to create a DWORD called ShowSecurityPage.
3.A value of 1 (Numeric one) means on (show security tab), whilst 0 (Zero) means off.
4.Close the registry editor.
5.Close the Exchange System Manger, then reopen (no need for a reboot)
6.Right click on YourOrganization (Exchange), then click Properties.
7.Click the Security tab, then highlight the Domain Admins group.
8.Scroll down the permissions list and uncheck Deny for Send As and Receive As
9.Repeat the above step for the Enterprise Admins group.

Installing Windows XP using an external USB CD-ROM, DVD-ROM drive.
Due to high demands for portability and technological advances, laptops are getting smaller and faster. They are now as small as a notebook and just as productive as a workstation. Unfortunately, the smaller laptops are smaller because essential devices, such as CDROMs and floppy disk drives, are externally connected. To add to the problem, companies often use proprioteiry connections to these devices. What happens when it breaks and the replacement is twice as much as other external USB drives? What if you have to boot off of a CD to re-install an operating system because you just upgraded your new hard drive? What if your operating system is corrupted and you would like to start over new? All of these situations have one thing in common. It poses the question: How do I get the Windows Boot CD to boot off of my external CDROM if my bios doesn’t support booting from USB? The steps below will save you a lot of time and frustration.
1. Download the USB DOS driver and Save the file to your hard drive.
2. Use Winzip to extract the file. If you do not have the Winzip program you may get a shareware version here.
3. Extract the file, then open the folder named USBboot and execute the rawrite2.exe.
4. When prompted for the image name, enter dosboot.img
5. Enter the floppy drive as your destination drive, which in general is the A:
6. When it is done, reboot with this disk to use the USB devices.
7. If everything went well, you should have a drive R: for the CDROM drive. You are now ready to copy the I386 folder from the Windows 2000 or XP installation CD to the hard drive.
8. Hard Drives will most likely be C: (the next letter available).
9. At the prompt, go to the CDROM drive (R:) and run “Xcopy *.* /s C:”
10. Now go to the I386 folder (C:I386) then type Winnt.
11. Installation should now start. Follow instruction from your Operating System manual on how to install the OS. (Installation will take some time, Please be patient)
How Open Source software can help your company while leaving costs behind…
In it’s most simplistic definition, open source software is a free program that is created or maintained by groups of people, such as volunteer programmers. Those that work on it can freely read, redistribute, and modify the source code. Open source software is high quality, low cost (usually free), flexible and independent software for all businesses. Below are the many criterias associated with open source software that supports rapid evolution.
Benefits of Open Source Software for Small to Medium-sized businesses
For today’s businesses, the most important factors in determining what software program to use are: functionality, compatibility, cost, and customizability. Fortunately, open source software addresses all these criterias. The value derived from software that is lean (no unecessary functionalities), standardized, cost effective, and customizable is tremendous. Aside from the obvious direct cost savings, open source software also improves efficiency. Also, the frequent updates and improvements to the software offers quick solutions to problems that may arise and features that will be needed in the future. Lastly, the ability to rewrite the code specifically for your business enpowers your business work flow.
Virtualization for applications…
In brief, Microsoft SoftGrid helps IT shops lower costs and enhance service by reducing the complexity and labor involved in deploying applications to desktops, portable computers, and terminal servers, as well as the complexity of keeping applications up-to-date. The fact that SoftGrid runs applications locally is a key difference from past attempts at virtualization, based on technologies such as Microsoft Windows Server® Terminal Server or Citrix. Because that approach required applications to be centrally hosted and centrally run, it led to mushrooming growth in servers, along with an increase in both hardware purchase costs and hardware maintenance costs. Furthermore, to prevent application conflicts in multi-tenancy situations, IT shops had to create separate instances of servers to host the various applications—a practice that further encouraged the growth of server silos and that resulted in increased management complexity and higher administrative costs.
In contrast, SoftGrid technology offers the ability to deliver and manage applications centrally while allowing client computers to run the applications locally. This approach reduces both hardware proliferation issues and multi-tenancy application conflicts. It also provides all the benefits of SaaS—such as ease of access, ease of
distribution, and ease of management—to earlier client-server applications.
