What To Check If A Single User Can't Log On To Domain?

Sometimes a single user might be not able to log on to domain. You can follow the checklist given below:

Make sure:

• You can ping the domain controller from the user's computer. 
• There is no white space in the User's Home Profile in User's Property > Check it using the DSA.MSC.
• The user computer is configured with the correct DNS Server to find the domain controller > Check in TCP/IP property of the user's computer.
• The Computer Account in the domain for the user's computer is not missing > Check using the DSA.MSC
• The Computer Account in the domain is not disabled > Check using the DSA.MSC
• The Time between the domain controller and the client computer is synchronized > Check using Net Time command.
• The Domain Controller can be found > Check environment variables and check "LOGONSERVER" value or execute Nltest /DsGetDc:domain to re-locate the domain controller for the user.
