# E2 Shop System Error 5093: Causes and How to Troubleshoot > Source: https://netray.co/erp-help/e2-shop-system-error-5093-fix > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer We could not find an authoritative public definition of E2 error 5093, so treat any single-cause answer with caution. In practice, numbered E2 errors raised at login or while opening a module come from the client talking to the database: a changed server name, a SQL permission or login problem, a missing or mismatched driver, or a network or firewall change. Isolate which with the checks below and give Shoptech support the exact context. ## Kind error ## System job-shop-erp ## Erp E2 Shop System (Shoptech) ## Module Database / Client connection ## Query e2 shop system error 5093 ## Alternate Queries - shoptech e2 error 5093 - e2 shoptech error 5093 - e2 shop system database error ## Applies To E2 Shop System by Shoptech, client-server installations on SQL Server. Exact message wording differs by version, confirm with Shoptech support. ## Steps ### Isolate the cause of error 5093 **Items:** - Write down exactly where the error appears: at login, opening a particular module, printing a report, or saving a record. Take a screenshot of the full message. - Test whether it affects one workstation or all. If only one, suspect the client install, driver or local permissions. - Test from the server console. If it works there but not from clients, suspect network, DNS name, firewall or the share permissions on the E2 folder. - Confirm the SQL Server service is running and that the database is online and not in single-user or recovery state. - Check what changed recently: Windows updates, server rename, IP change, antivirus, SQL or E2 updates, new user accounts. - Verify the SQL login E2 uses still exists, is enabled, and has rights on the E2 database. Do not change roles blindly, record the current state first. - Take a verified backup before any repair, then contact Shoptech support with the message, the version and the findings from steps 1 to 5. ## Sections ### How to read a numbered error **Body:** A bare number tells you almost nothing without the code path that raised it. The most useful information is the context: which action, which user, which machine, and what changed. The same number can surface from different layers, such as the application, the database driver or the operating system. Search results for numbered E2 errors often repeat advice for unrelated codes. Be skeptical of any forum answer that does not ask where the error appears. ### The usual suspects **Body:** Connection and permission changes cause a large share of post-update errors. A server renamed or moved to a new IP leaves clients pointing at a name that no longer resolves. A Windows update can change TLS or driver defaults. A new antivirus policy can block the E2 client from its data folder. Check the Windows Event Viewer on both the client and the server at the exact time of the error, as well as the SQL Server error log. These often name the underlying cause even when E2 shows only a number. ### Before you call support **Body:** Gather the E2 version and build, SQL Server version, operating system versions, screenshot, time of error and a list of recent changes. Support can then work out whether it is a known issue in your build or an environmental problem, which is much faster than a general description. ## Pitfalls - Reinstalling the client on every PC before checking whether the server side is healthy. - Granting broad SQL permissions as a quick test and leaving them in place. - Trying fixes without a fresh verified backup. - Following forum advice written for a different error number. ## Ai Angle For shops with a tangle of tribal fixes, a private assistant over your own support notes, event logs and past tickets can find how a similar error was resolved last time without sending any data outside. Netray's DataRay does exactly that kind of on-prem chat over documents and logs. ## Faq ### What does E2 error 5093 mean? **Answer:** We could not confirm a published meaning, so we do not assert one. Numbered E2 errors at login or module open typically trace to the database connection, permissions or drivers. Confirm with Shoptech support using the exact message and version. ### Does the error mean my data is corrupt? **Answer:** Not necessarily. Most connection-type errors do not damage data. Still, take a verified backup before any change, and check the SQL Server log for signs of database problems. ### Who supports E2 Shop System? **Answer:** Shoptech provides support through its support plans, and many shops also use independent E2 consultants. Have your customer or serial information ready. ### Can I fix this myself? **Answer:** Often you can isolate it, for example a changed server name or permission. Anything that touches the database should follow a backup and ideally a call with support. ## Search terms e2 shop system error 5093, shoptech e2 error 5093, e2 shoptech error, e2 shop system troubleshooting, e2 database connection error, shoptech e2 support, e2 shop system sql server, e2 mfg system error --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
