ivy & server access errors - ivy

Question

We have an Ivy repository accessible via HTTP. It can be accessed by several machines without problems but on a Windows machine we get a server access error.
[ivy:retrieve] Loading jar:file:/C:/Users/moserma/.ant/lib/ivy-2.3.0-rc1.jar!/org/apache/ivy/core/settings/ivy.properties

[ivy:retrieve] WARN: http://ivy.ethz.ch/checkstyle/checkstyle-all/5.5/checkstyle-all-5.5.jar
Now there are no firewalls or proxies involved and the URLs are accessible without problems with other tools (e.g., a browser, curl, wget, ...). For example:
$ curl http://ivy.ethz.ch/checkstyle/checkstyle-all/5.5/ivy-5.5.xml
<ivy-module version="2.0">
<info organisation="checkstyle" module="checkstyle-all" revision="5.5" status="integration" publication="20120806133612"/>
<publications>
<artifact name="checkstyle-all" type="jar" ext="jar"/>
</publications>
</ivy-module>
On the server side the logs show nothing: no errors not even a connection
EDIT ivysettings.xml should be OK since they can be used without problems with Mac OS X and Linux:
<ivysettings>
<settings defaultResolver = "ETHZ-HTTP" >
<caches defaultCacheDir = "${ivy.settings.dir}/ivy-cache" />
</settings>
<resolvers>
<url name="ETHZ-HTTP">
<ivy pattern="http://ivy.ethz.ch/[organisation]/[module]/[revision]/[artifact]-[revision].xml" />
<artifact pattern="http://ivy.ethz.ch/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
</url>
</resolvers>
</ivysettings>
Any hint?

Maybe there is a firewall on your Windows machine which is blocking Java from doing any network ?
Try this simple ant build.xml file to test it:
<project>
<get src="http://ivy.ethz.ch/checkstyle/checkstyle-all/5.5/ivy-5.5.xml" dest="ivy-5.5.xml" />
</project>
