Windows and Linux Real time scenarios and answers that Works

Open Windows Explorer and navigate to the "C:WindowsSystem32" directory. Within this directory, locate the "gpedit.msc" file and double-click on it.  This should open up the Group Policy Editor.  Navigate to "User Configuration -> Administrative Templates -> Start Menu and Taskbar". On the right side of the screen, locate the policy labeled "Remove Run menu from Start Menu" and double-click on it.  Set this policy to "disabled". Click the Apply button, followed by the OK button. Within a few minutes the Run option should become available again. This set of instructions will work on Windows XP Professional Edition, but I am pretty sure that the gpedit.msc file is not available on Windows XP Home Edition.  If this is the edition you are on, then go to "http://www.kellys-korner-xp.com/xp_tweaks.htm" and locate the link labeled "Restore the Run Command". This should provide you with a file tha...

In this post I am going to expalin about "how do we know the broadcast address of the network" ? Example Provide the broadcast address for the following: IP Address: 221.240.224.121 Subnet mask: 255.255.255.248 Method I currently use. 2^Nth - 2 = number of usable subnets.  2^5 - 2 = 30 subs 256 - last mask number = first network 256-248 = 8 or 221.240.224.8 Now add network range to itself equal to the total subnets calculated earlier to find all range start points. Stop when ip address falls in a range. .8 .16 .24 ... .112 .120 (bingo) Add range - 1 to start point to find broadcast. 120 + (8 - 1) = 127. That is a pretty long process. I do know of 2 sort cuts mainly divide till you find the range you want. Like start with 121/8 = 15.125 so to high try 120/8 =15 whole number so start of a range. Also instead of adding subnet start with range - 1. Just go up a range and subtract one. 120 jump to 128 subtract 1 = 127. Anyone have any poin...

In Rhel 5 virtualization can be done in two ways Para Virtualization Full Virtualization Para virtualization : Min 512 MB Ram and CPU must support PAE Flag Full Virtualization :  Min 512 MB Ram and CPU which supports VMX (Intel Processors and vm AMD) We must install xen Kernel, which supports virtualization to be supported in the server and we should install virt-manager, Just like Vmware in windows #yum install kernel-xen-2.6.***** #yum install virt-manager Whenever we install the xen kernel the following services will start libvirtd xend Now to open virt manager in the server type the following command : #virt-manager click on New --> forward -->VM1 (Guest os name)  --> forward --> ftp://server1.example.com/pub (path that we have copied the RHEL5 DVD ) --> Normal Disk Partition (Seperate partition) ...and follow the on screen instructions Note : to check the cpu info #cat /proc/cpuinfo The entire above process is para - virtu...

I have a problem with my laptop. I cannot seem to connect to my wireless router at home. I see the strong signal and put in the correct passkey, but all I see is "Acquiring network address." I had another laptop using a PCMCIA Wireless card and could not connect. So at first I assummed it was the router problem, then I just bought a brand new router. Then it still doesnt work and gives me the same message. My brother laptop however works. The thing is that my laptop is newer than his. I have no idea what the problem is. It just keeps trying to connect forever and forever, has that message "Acquiring network address." I read on some posts that it could be a DHCP problem? I have no idea how to fix that. Can someone help? Thanks.  Sollution :   Hi there This can often be an issue with security encryption. There may be a wrong key entered or the client adaptor does not support the encryption used. To try and solve this first change the SSID o...
