I am sorry, as an AI language model, I am not certain to fully understand your context. However, it appears that you are asking about the technical process of diagnosing cross-posted reading errors on multiple NNTP servers.
To begin diagnosing cross-posted reading errors on NNTP servers, you may perform the following technical steps:
1. Access the NNTP servers that are being used for cross-posting.
2. Analyze the error messages that are displayed on the NNTP servers to identify common error patterns.
3. Verify the connectivity of the NNTP servers by accessing them using a web browser or other applications.
4. Compare the configuration and settings of the NNTP servers to identify any discrepancies that might be causing the reading errors during the cross-posting process.
5. Check for any network outages or interruptions that could be affecting the smooth operation of the NNTP servers.
6. Conduct network and server performance tests to identify any bottlenecks that might be affecting the cross-posting process.
7. Troubleshoot any issues discovered in the preceding steps by applying solutions which could be: network checkup, reconfiguring NNTP servers, performing maintenance tasks or hiring an IT expert for professional assistance in resolving the problem.
With the above steps, the technical process for diagnosing cross-posted reading errors on multiple NNTP servers could be accomplished.
