SYMPTOMS
When you try to set up the Exchange Server Load Simulation tool (Loadsim.exe), and then try to create a topology, you may receive an error message that is similar to the following:

Nov 21 08:06:59: -Begin Topology Creation-

Nov 21 08:06:59: ERROR: LDAP add: (CN=Jpmigdfaaa WIN2K-ADV,OU=WIN2K-ADV,OU=Loadsim Users,DC=kazoocon,DC=com) error: Unwilling To Perform

Nov 21 08:06:59: -End Topology Creation-



CAUSE
This issue occurs if you use Loadsim.exe in a domain where password policies prevent null passwords. By default, all accounts that are created by Loadsim.exe have null passwords. Therefore, Loadsim.exe cannot create new accounts, and you receive the error message that is listed in the &quot;Symptoms&quot; section of this article.



RESOLUTION
To resolve this issue:  Turn off the password policy:  On the domain controller computer, click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers. Right-click the domain object where the Exchange server is located, and then click Properties. Click the Group Policy tab, click Default Domain Policy, and then click Edit. In the Group Policy dialog box, under Computer Configuration, expand Windows Settings, expand Security Settings, expand Account Policies, and then click Password Policies. In the right pane of the Group Policy dialog box, double-click Minimum password length, and then note the minimum password length that appears in the Password must be at least box. Change this value to zero (0), and then click OK. Restart the domain controller computer.</li></ol> </li> Start Loadsim.exe on the client computer. On the Run menu, click Create Topology.</li> Change the password that Loadsim.exe created for the users to a password that complies with the domain password policy: <ol style="list-style-type: lower-alpha;"> On the domain controller computer, click Start, click Run, type cmd in the Open box, and then press ENTER.</li> At the command prompt, type net user > Users.txt, and then press ENTER.</li> Type notepad Users.txt, and then press ENTER.</li> In Notepad, edit the list of users so that only the users who are created by Loadsim.exe are left. Save the file as Users.txt, and then quit Notepad.</li> At the command prompt, type the following three commands, and then press ENTER after each command:

FOR /F &quot;tokens=1,2,3 delims= &quot; %i IN (Users.txt) DO net user %i LoadSimExe

FOR /F &quot;tokens=1,2,3 delims= &quot; %i IN (Users.txt) DO net user %j LoadSimExe

FOR /F &quot;tokens=1,2,3 delims= &quot; %i IN (Users.txt) DO net user %k LoadSimExe

Note that by running these commands all users who are listed in the Users.txt file have their passwords changed to &quot;LoadSimExe&quot;. If your password policy requires a different password, modify the commands accordingly.</li></ol> </li> Turn on the domain password policy: <ol style="list-style-type: lower-alpha;"> On the domain controller computer, click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.</li> Right-click the domain object where the Exchange server is located, and then click Properties.</li> Click the Group Policy tab, click Default Domain Policy, and then click Edit.</li> In the Group Policy dialog box, under Computer Configuration, expand Windows Settings, expand Security Settings, expand Account Policies, and then click Password Policies.</li> In the right pane of the Group Policy dialog box, double-click Minimum password length, and then type the minimum password length in the No password required box. Click OK.</li> Restart the domain controller computer.</li></ol> </li> Continue with Exchange Server Load Simulation.</li></ol>
