Here’s a link to thorough guides and reset information for Snap Servers.  Link

Remember when connecting Snap Servers with Vista and 7 computers you may have to adjust NTLM -

You may have devices on your network that you can no longer connect (Vista/Windows 7) to or you may not be able to network to Windows XP (for whatever reason, this works).  Actually this changes settings to accept NTLMv1 and NTLMv2 so that you can connect to Samba Servers, Snap Servers, Older Windows Computers or whatever….

1. Go to Run, Type Regedit and open this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

2. If it doesn’t exist, create a DWORD value named
LmCompatibilityLevel

3. Set the value to 1

4. Reboot

One of the best ways to speed up your computer of course is to uninstall old programs.   A recent article showed that the installation of multiple programs on any computer could slow the computer’s boot time, response time and even the shutdown.

Just like programs;  installing network cards, video cards, wireless cards, usb drives and other hardware and even software will put drivers in your computer.  These non exsistant devices can be seen in the device manager by going to a command prompt as an administrator and typing – set devmgr_show_nonpresent_devices=1

Then open the device manager and click on View and Show Hidden Devices.  You will then see ‘faded’ devices that are still loading in the device manager.   These devices are hardware and/or software (yes, even software will load drivers that control hardware) that no longer are installed on your computer.

Note:  In regards to the software drivers – even if you uninstall the software many antivirus programs and firewalls leave junk behind.

Always use caution when removing drivers, editing the registry or working with any configuration that changes your system.

Go through these devices and remove any older hardware you know no longer exsist.  Rebooting your computer should result in a quicker response time.

Networking and Computer professionals often use the command prompt to run commands.  To open a command prompt, users normally click on Start/Run or Start/Search and type CMD.   In Windows 7, this will be c:\user\yourname.

If you would like to open a command prompt in Vista or Windows 7, simply right click on the folder you want while holding down on the shift  and you will be given an option to open a command prompt.  If you continue, the command prompt will open and the path will be presented to you of  the folder you right clicked on as an administrator.
