The regional settings of the operating system wherein your BizTalk Server is hosted, affects how the numbers/date are formatted. This in some cases, becomes a problem when trying to insert data in SQL Server using WCF-SQL.

For instance if the server is setup to use Dutch regional settings, the decimal number is separated by (,) comma. When you try to insert a data for instance 10.001, it becomes 10001. To fix the problem, you need to change the regional settings of the service account wherein the host instance is running.

Basically there are two things you can do.

One is to logon the account -> Go to regional settings -> Change the number formatting.

Now, if it’s impossible to login the account, you can fix it by changing the registry settings, for this you need the SID of the user account.

Updating Regional settings of an account using registry:

1. Open Regedit.

2. To get the SID, navigate to HKLM\SOFTWARE\Microsoft\Windows NT\ProfileList

Browse to every folder below and using the value in ProfileImagePath, you can determine the correct user account.

Then use the SId of the folder.

3. Once you have the GUID, browse to: HKEY_USERS\\Control Panel\International

Change the string values, for Decimal, change the sDecimal value.
