If the dtlogin daemon cannot start the Xsun or Xnewt server properly, the following configuration files might be corrupted:

/etc/dt/config/Xservers
/etc/dt/config/Xconfig

The following procedure explains how to correct this problem.

Note

This procedure shows output from a simplified example. Your output may have tens of lines between the BEGIN SUNRAY CONFIGURATION and END SUNRAY CONFIGURATION comments.

As a user of the Sun Ray server, open a shell window and compare the /usr/dt/config/Xservers and /etc/dt/config/Xservers files.
```
% diff /usr/dt/config/Xservers /etc/dt/config/Xservers
```
This command compares a known good file with the suspect file. The output should be similar to the following example.
```
106a107,130
> # BEGIN SUNRAY CONFIGURATION
> :3 SunRay local@none /etc/opt/SUNWut/basedir/lib/utxsun :3 -nobanner
.
.
> :18 SunRay local@none /etc/opt/SUNWut/basedir/lib/utxsun :18 -nobanner
> # END SUNRAY CONFIGURATION
```
The first line of output contains 106a107,130. The 106 means that the two files are identical to the 106th line of the files. The a107,130 means that the information on lines 107 through 130 of the second file would have to be added to the first file to make it the same as the second file.
If your output shows the first three digits to be a number less than 100, the /etc/dt/config/Xservers file is corrupt.

Compare the /usr/dt/config/Xconfig and /etc/dt/config/Xconfig files.

% diff /usr/dt/config/Xconfig /etc/dt/config/Xconfig

The output should be similar to the following example.

156a157,180
> # BEGIN SUNRAY CONFIGURATION
> Dtlogin.*_8.environment: SUN_SUNRAY_TOKEN=ZeroAdmin.m1.at88sc1608.6d0400aa
.
.
> Dtlogin.*_9.environment: SUN_SUNRAY_TOKEN=ZeroAdmin.m1.at88sc1608.a10100aa
> # END SUNRAY CONFIGURATION

If your output shows the first three digits to be a number less than 154, the /etc/dt/config/Xconfig file is corrupt.

If either file is corrupted, continue this procedure to replace the configuration files.
Become superuser on the Sun Ray server and shut down the Sun Ray Client services.
Note
Replacing the Xservers file requires shutting down all Sun Ray Client services. Remember to inform users of the outage.
```
# /opt/SUNWut/sbin/utstop
```
Replace the Xservers and Xconfig files as appropriate.
```
# /bin/cp -p /usr/dt/config/Xservers /etc/dt/config/Xservers
# /bin/cp -p /usr/dt/config/Xconfig /etc/dt/config/Xconfig
```
Note
For headless servers, comment out or remove the :0 entry from the Xservers file.
Re-initialize the authentication policy.
```
# /opt/SUNWut/sbin/utstart -c
```
The extra lines within the previous Xservers and Xconfig files are automatically rebuilt.
