# Troubleshooting

## Slow lookups

Sometimes with certain server hosts, their networks tend to respond slower for a variety of reasons. In MySQL there is a process as part of each login in which a DNS lookup is run before the CAD or other database users can be allowed in.

With slow DNS server settings, this can sometimes cause lookups to take 5-20 seconds in the CAD. We are going to show you one way to resolve this in MySQL Server/MariaDB Server.

1\. Open your my.ini configuration file for your MySQL server. If you are using XAMPP simply open the XAMPP Control Panel and click `Config` then `my.ini` from the line for your MySQL Module.

![XAMPP - Opening my.ini configuration file](/files/2WSb4eqfP6HR6YL09EEq)

2\. With the my.ini configuration file open, scroll down till you find the "\[mysqld]" section and add the following line right under `[mysqld]`

> skip-name-resolve

![MySQL my.ini configuration file](/files/gpiqSD8KujA41ZnmeR4T)

3\. Save the my.ini file and then restart your MySQL server. For XAMPP simply click Stop in the XAMPP Control Panel then click Start.

Your lookups in Sonoran CAD with DBSync enabled should now be faster. If your lookup speed is still slow (ie. takes over 5 seconds) this is usually due to much greater issues either with the performance of your server or network.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sonoransoftware.com/cad/integration-plugins/database-sync-and-merge/troubleshooting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
