Intermittent Web Service Connection

Hi,

I have a desktop Air app that connects to a web service on a citrix network.

The connection is intermittent and seemingly random..sometimes working as expected and sometimes it just refuses to connect. Downtime is usually for anything from 5 mins to 1 hour.

I have place a crossdomain policy file at wwwroot:

Code:

---

<?xml version="1.0"?>
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
</cross-domain-policy>

---

and another within the web service folder:

Code:

---

<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="*" secure="false" />
</cross-domain-policy>

---

and place this line in my code before connecting to the service:

Code:

---

Security.loadPolicyFile("http://***************.local/S200WebService/crossdomain.xml");

---

As it is an intermittent connection I suspect that it is not a crossdomain issue but it was worth trying but it did nothing.

I get this fault :

Code:

---

[RPC Fault faultString="" faultCode="Server.Error.Request" faultDetail="null"]

Anybody had a similar intermittent issue with network web services at all?

Any help appreciated.

Many Thanks
