Fix the “Running out of free space” warning

NOT AVAILABLE IN SAAS. Contact your Syteca vendor or the Syteca Support team to change this value in a SaaS environment.
The System Health Transaction log adds a “Running out of free space” warning when the storage location used for Syteca data has less than an average of 2.5 GB of free space per Client. For example, with 10 Clients installed, the location needs more than 25 GB free to avoid this warning.
1

Open the Application Server settings file

On the Application Server computer, open EkranServer.Settings.config (by default in C:\Program Files\Ekran System\Ekran System\Server).
2

Add the warning threshold key

This sets the minimum required average free space per Client, in MB, before the warning is logged.
3

Save and restart the Application Server

Save the file, then restart the EkranServer service from Task Manager.

Fix ERR_SSL_KEY_USAGE_INCOMPATIBLE in Chrome

Chrome version 119.0.6045.160 and later require the Digital Signature key usage parameter on any certificate used to serve the Management Tool over HTTPS. Without it, Chrome blocks the login page with this error.

​
1. Create a trusted self-signed certificate

1

Open PowerShell

Run Windows PowerShell as administrator.
2

Generate the certificate

  • -DnsName: every name used to reach the server — hostname, domain name, and IP address.
  • -KeyLength: 2048 is the minimum; some browsers warn below 4096.
  • -CertStoreLocation: only LocalMachine\My or CurrentUser\My are valid.
  • -NotAfter: the certificate’s expiration date.

​
2. Export the certificate

1

Open the Certificates snap-in

Press Windows+R, enter mmc, press Enter, and click Yes on the User Account Control prompt. Select File > Add/Remove Snap-in, choose Certificates, and click Add.
2

Target the current user account

Select My user account, click Next, then navigate to Certificates - Current User > Personal > Certificates.
3

Export the certificate and private key

Right-click the certificate, select All Tasks > Export, then on the wizard select Yes, export the private key.
4

Set the export format

Select Include all certificates in the certification path if possible, Export all extended properties, and Enable certificate privacy.
5

Set a password and save

Enter and confirm a password, choose a file location and name, then finish the wizard.

​
3. Add the certificate to Trusted Root Certification Authorities

1

Install the exported certificate

Open the folder where the certificate was exported, right-click it, and select Install PFX.
2

Select the Local Machine store

On the Certificate Import Wizard, select Local Machine, then continue past File to Import.
3

Enter the private key password

Enter the certificate’s password on Private key protection.
4

Place it in Trusted Root Certification Authorities

Select Place all certificates in the following store, choose Trusted Root Certification Authorities, and finish the wizard.

​
4. Bind the certificate in IIS

1

Open IIS Manager

Open Internet Information Services (IIS) Manager.
2

Import the certificate

In Connections, select the target computer, open Server Certificates, click Import (in the Actions pane), select the certificate, and enter its password.
3

Bind it to the default site

Under Sites, select Default Web Site, click Bindings, double-click the https record, confirm Type is https, and select the imported certificate under SSL certificate.
4

Close and restart Chrome

Click Close, then restart Chrome. The Management Tool should now open without the error.

Internet Explorer is no longer supported from Syteca version 7.0 onward. This section is preserved for legacy environments only.

1

Open Internet Options

In Internet Explorer, click Tools > Internet Options.
2

Open Trusted Sites

Select the Security tab, then Trusted Sites.
3

Lower the security level

Set the security level to Low.
4

Disable Protected Mode

Clear the Enable Protected Mode checkbox.
5

Add the site and close

Click Sites, add the Management Tool address, click Close, then OK.

System update issues

NOT AVAILABLE IN SAAS.
Application Server logs show:
This happens when a file (not a folder) named Program exists in the SystemDrive root, or a file named Common exists in ProgramFiles — Windows Service Control Manager expects SystemDrive\Program and Program Files\Common to be folders, and can’t locate them if they’re files instead. Rename or delete the conflicting file(s), then restart the system.
  • If the keys were activated online, they resynchronize automatically on the Application Server’s first startup after the update — an active internet connection is required at that moment.
  • If the keys were activated offline, add them again manually in the Management Tool.
Contact your account manager or the Syteca Support team.
Application Server logs show entries like:
1

Stop the Application Server

Stop the EkranServer service via Task Manager.
2

Open the settings file

Open EkranServer.Settings.config (by default in C:\Program Files\Ekran System\Ekran System\Server).
3

Remove the pool size overrides

Delete these two lines:
4

Save and restart

Save the file, then start the EkranServer service again via Task Manager.

Issues with monitored sessions

Confirm you have the Viewing Monitoring Results permission for that Client.
  • If a user types continuously, stops, then switches windows within 3 seconds, the keystrokes attach to a blank capture.
  • Minimizing an RDP connection window while accessing a Client also produces a blank capture.
On the Client, open Editing Client > User Activity Recording and confirm Enable screen capture recording along with user activity recording is selected.
The Client computer has multiple monitors, and the capture shows all of them.
  • Confirm you have the Viewing Text Data permission for that Client.
  • Confirm Enable clipboard monitoring is selected in the Client’s configuration.
If any user activity recording option besides Record user activity periodically is enabled, captures follow user activity instead of a fixed interval.
It was likely captured mid-animation, if the Client computer has smooth interface animations enabled.
The Client is configured for grayscale capture. Check the Bit depth setting in the Client’s configuration.
Capture times reflect the Client computer’s clock, not the viewer’s.
Check whether the Client computer’s time settings have changed.
