Webservice File or assembly name was not found.

[Gene Vangampelaere]

I have a webservice that provides a list with updates (Class
SoftwareUpdate). The list is an ArrayList :

Public Class SoftwareUpdates
Inherits ArrayList

My WebMethod looks like this :

<WebMethod()> _
Public Function GetLaatsteUpdates(ByVal Ziekenhuisnummer As String, _
ByVal GUID As String, _
ByVal HuidigeVersie As String) As _
<XmlElement(GetType(SoftwareUpdate))>
SoftwareUpdates

When I call the webmethod I always get this error message:
(the name of the missing assembly changes randomly)

System.Web.Services.Protocols.SoapException: Server was unable to process
request. --> File or assembly name ikdtfozb.dll, or one of its dependencies,
was not found.

at
System.Web.Services.Protocols.SoapHttpClientProtoc ol.ReadResponse(SoapClientMessage
message, WebResponse response, Stream responseStream, Boolean asyncCall)

at System.Web.Services.Protocols.SoapHttpClientProtoc ol.Invoke(String
methodName, Object[] parameters)

at TestApplication.localhost.Updates.GetLaatsteUpdate s(String
Ziekenhuisnummer, String GUID, String HuidigeVersie) in
C:\dotNet\SoftwareUpdates\TestApplication\Web
References\localhost\Reference.vb:line 43

at TestApplication.Form1.cmdUpdates_Click(Object sender, EventArgs e) in
C:\dotNet\SoftwareUpdates\TestApplication\Form1.vb : line 175
I did some reseach on Google and I read something about permission on the
WINDOWS\TEMP folder. I add Full Control to everyone but I still get this
error.

Is there anyone that can give me some help ?

Kind regards,

Gene
