The Option Explicit statement requires you to declare all variables before they can be used. You must have Option Explicit as the first executable statement in your script. After that, you must use Dim , Private , Public , or ReDim to declare all variables. To novice scripters, this may seem more of a nussance then a helpful tool. Once you begin scripting longer and longer code, you will appricate it. It will help prevent you from accidentally decalring two variables of the same name. Without this statement, you could just declase a variable anywhere. Also, should you mistype the variable later on, an error message will help you locate the problem. Option Explicit will help keep your code clean and organized.

To ensure that your clients are in sync with your domain controllers, you can call this command from a logon script. Net time // servername /set /yes Authentication requires that the system clocks of your clients be within 5 minutes of the system time on your domain controllers. If the deviation occurs on a server, then you may want to consider running this in a batch file as a scheduled task every day. Remember to use an account with the right level of user rights to run this command. http://support.microsoft.com/kb/314090

User rights give the user (or group) the ability to perform certain activities on the computer (or other computers). The difference between User Rights and Permissions is this: User rights: · Attached to the user account. · Allow the user to perform actions on the computer (or the network) Permissions: · Determine the level of access a user has to an object in Active Director. · Attached to the object. In Sever 2003, there are 39 different user rights. To get a detailed explanation of each user right and the default members: · Open Local Security Policy (or Default Domain Controller Security Settings) · Expand Local Policy · Right Click User Rights and select Help . · A list of all user rights is listed in the right hand column.

All of us road warriors know, eating healthy is a challenge while we are on the job. This past week my students invited me to a Chinese buffet. I'm very glad that another health conscious member of the group came along. It helped me to resist the temptation of gorging on all that wonderful food. I highly recommend eating 6 times a day. Doing so puts your bodies genetics to work for you. As long as your body thinks that food is plentiful, it will not try to store it as fat. Of course, you cannot eat Mc Donalds 6 times a day. I try to keep fresh fruit with me and eat it during our class breaks. When asked while I am not partaking in the Krispy Kreams, I simply remind them that I am in the military. Usually that is all that I need to say. After work, I usually change into some shorts and go for a run. I try to stay at hotels with a refrigerator and a microwave. That way I can at least do a little cooking for myself and stay out of the restaurants.

The link below will allow you to download the adminpak for Server 2003. You can also get it from your servers at %windir%\system32\adminpak.msi. This does not work for 64 bit systems. Microsoft recommends that you utilize remote desktop for administration for a 64 bit system. http://www.microsoft.com/downloads/details.aspx?familyid=C16AE515-C8F4-47EF-A1E4-A8DCBACFF8E3&displaylang=en

The maximum VHD size in Hyper V is 2040GB (8GBs short of 2TB). Should you need more, there is an option. You can utilize passthrough disk to exceed this limitation. This passthrough disk can be a physical disk on the host, or on a SAN. Also, if your are using a SAN, you will lose you Snap Shot capability.

Objective: join a server core to a Windows domain. Requirements: You need to know the username and password of an account that has permission to join a computer to the domain in question. Type NETDOM JOIN machine /Domain: DomainName /userd: username /Passwordd:* Machine is the name of the computer to be joined to the domain. DomainName is the name of the domain that is being joined. UserD is the username of an account with the Add Workstation to Domain user right. PasswordD:* tells the computer that you will manually enter the password for this user and to prompt you for it. Opitonally, you can specify which OU to place this computer object in. This is preferable if Active Directory is set to place all new computer objects in the Computers container. Since we cannot apply Group Policy to the Computers container, this represents a hole in your security. To do this, add this line after the domain name: /OU: ou path. A common error when executing this command is in typing the ...

Providing alternate credentials allows scripts to run while a non administrator is logged into the client. I found script samples for this on ScriptingAnswers.com http://www.scriptinganswers.com/essentials/index.php/2008/02/15/alternate-credentials-adsi-and-wmi/ The following code was taken from WindowsITPro.comL http://windowsitpro.com/windowsscripting/article/articleid/39114/rem-running-a-script-with-alternate-credentials.html LISTING 1: ADSI Script That Uses Alternate Credentials Const ADS_SECURE_AUTHENTICATION = 1 strUserDN = "cn=Administrator,cn=Users,dc=acme,dc=com"strPassword = "bXk23s8w" ' BEGIN CALLOUT ASet objRoot = GetObject("LDAP:")Set objDomain = _ objRoot.OpenDSObject("LDAP://dc=acme,dc=com", _ strUserDN, strPassword, ADS_SECURE_AUTHENTICATION)' END CALLOUT A Set objOU = objDomain.Create("organizationalUnit", "ou=Students")objOU.Put "Description", "Student OU"objOU.Set...

Objective: Set a static IP Address This example assumes that you want to configure a static IP addres of 10.10.1.10 with a subnet mask of 255.255.0.0 of a Windows 2008 Server Core. Task 1: Get the name of the interface you want to set an IP address for. · Type netsh interface ipv4 show interfaces · Press Enter · Record the name of the interface you want to set a static IP address for. Sample output is below. Idx Met MTU State Name --- --- ----- ----------- ------------------- 3 5 1500 Connected Local Area Connection · Local Area Connection is the name we are interested in. · To simplify the typing, you can also user the Idx value of 3 . Task 2: Set the IP Address · Type netsh interface ipv4 set address name=3 source=static address=10.10.1.10 mask=255.255.0.0 · Optionally, you can add a gateway address by appending gateway= address to the end of the command. · In the Name parameter, we used the Idx value. We could have also typed “ Local Area Network” . Task 3: Verify the address c...

Windows 7 Bitlocker-to-Go allows you to encrypt information on an entire volume. Even if the volume is a removable drive or USB memory key. To support the use of your portable devices, XP SP3 and Vista SP1 can open the encrypted key. When you allow the key to autoplay, an application on the unencrypted portion of the drive brings up the BitLocker –to-Go reader and asks for the password. If you explore the device without using the reader, you will only see the unencrypted portion of the drive containing the reader software. Also, if you look at the properties of the drive, it is completely filled. The encrypted side will reserve all the space on the volume, minus the small portion for the reader.
